I seem to have triggered something by accident. Both the power and the charge LEDs are on, solid, when I plug in the board and the power switch is set to the on position. Additionally I can no longer upload sketches. When I connect the serial basic to program, the RX light stays on. The fact that it wasn't fixed by unplugging it makes me very concerned.<p>Anyone know what I might have done, or how I can fix it? Did I brick this Thing somehow?</p></p>

To be more specific, you should be attaching the switch to your power supply (into the board) and not the board itself. (<em>If you look at the <a href="https://cdn.sparkfun.com/datasheets/Wireless/WiFi/SparkFun_ESP8266_Thing.pdf" rel="nofollow">schematics</a> for the ESP8266 Thing, there are no breakout pins on the board to attach a power switch.</em>)</p></p>

Where can I connect the two ends of the switch onto the board? I do not see any connectors nor PTH's for an external switch. Other than unsoldering the currently embedded switch and soldering an external switch to it, I don't see an easy solution.</p>

After over an hour of trying different things and getting only gibberish in the serial monitor, I decided to disconnect the FTDI cable and try my battery power options. All 3 work with the serial header disconnected. So, for development and debugging, run your ESP8266 off USB power, which works fine with the FTDI cable connected, then work off your power selection in deployment.</p><p>If there is something I am missing about this, I'd love to hear a suggestion. I need to power an H-bridge at 6V, so I thought a voltage regulator off that main supply could power the Vin pin on the Thing, since the Vin range on the spec sheet is 3.3 - 5.5.V.</p><p>So for now, while I work on my code, I'll power the H-bridge only off the 6V and the Thing from the USB micro connection. I can't wait to get this all pulled together. Now that I have learned some off the tricks to using this Thing, I already have a few other ideas for it.</p></p>

I want to revert back to the default firmware, can I download it or is it possible to force a reset on the board to get back to factory fresh?

I what to no if this would be secure enough to be a internet device that could be connected to two office servers to connect to there power switch, reset switch, power led & hdd led?<p>I have two in house servers that we need to be able to shut down when lighting storms are approaching then boot back up after they have passed. Also sometimes the servers locks up and we need to reboot them to get them back going. Note we have remote access to these systems but if it locked up or crash running the remote software and no one is at the office at 2 am, this should give us the ability to reboot them independent of the OS.</p><p>We need to make sure it has secure access to this board so just not anyone can shut down or reset these systems.</p></p>

Almost as if I was trying to beat a WDT reset. I'll try the stuff above on my next one if it causes issues. So far 2 of 3 are doing it. One works fine all the time.<p>******Update*******
Got bit by a fake FTDI chip. I had ordered some 3.3/5v usb to serials on Amazon for a good price. It actually cost me 4 days of my time fighting and researching to figure out what was wrong. I had 2 of them so when I tried cables and power supplies and even a second board, I thought it had to be the Thing. Then I found I had grabbed an RFD22121 usb to serial adapter. So I rigged it to the thing. The only problem was it apparently doesn't pull down DTR, so then I hooked the fake ftdi to the DTR on the thing, opened putty on a second com port, the Thing dropped right into download mode and took sketch after sketch. Amazing. Sometimes saving a few bucks isn't worth it.</p></p>

With or without the jumper, i get only griberish which as a result makes the use of AT commands impossible with this board. I do not advise people to buy this board if you need to have access to AT commands. it works only with uploading sketches which is very disappointing and frustrating for an ESP8266 board that is twice the price of a standard module (on which by the way i have very easily access to AT commands on serial monitor).</p>

<p>serv</p>
<p>Well, it looks like the board doesn't like it :)
I tried with a not-so-cheap servo drawing 400 mA with no load according to its datasheet (PowerHD 1501MG), with the board plugged on my laptop USB. It worked, and after a second it started to smoke and stink hard. I unplugged everything quickly, and the board is not dead, but I expect some surprises in the future ^^
It seems to be ok with a cheap SG90 servo (which running current's value is mysterious, but obviously less than for 1501MG), however I still don't know the exact limit...</p></blockquote>

If you're using USB, you can probably expect around 500mA (minus a little bit for whatever the ESP8266 is pulling).<p>If you're using a battery, the supply capacity will vary, but you should be able to get enough out of most LiPo's to drive servo. If you're battery doesn't have a lower limit, the Q1 MOSFET may end up limiting the current to around 2.5A.</p><p>And, yes, every GPIO has PWM-capabilities -- assuming your using the Arduino addon.</p></p>

Have recently discovered that my unit was manufactured with the u.FL mounted "backward" - the center pin is connected to the "NC" pad instead of the signal input. Turns out that not having an antenna connected causes BAD things to happen, like processor resets when trying to access WiFi. Check the continuity if you're planning on using the u.FL connector.</p>

While sparkfun has setup a nice repository for the thing board itself might also be useful to add a bit to the hookup guide about getting the other libraries for esp8266. But now I got everything working great and have a remote temperature sensor for the pool.</p>

So you'll need a jumper wire that you can easily connect/disconnect. Wire GPIO0 to GND if you're programming, leave the pin floating (there's an on-board pull-up resistor) if you want to run its program.</p><p>After you've wired GPIO0 to GND, reset the ESP8266 by sliding the on/off switch off then on. It should now be in bootloader mode, and you should be able to upload a sketch to it with just GND, RX, and TX wired up from your RS232 Shifter.</p></p>

I love this Thing!! It will turn a led on and off and it will post to phant...the sparkfun tutorials Rock.. I actually programed my thing in under 3 hours (including updating arduino ide and installing stuff) it was awesome.
So here are my questions.
1. I can freely use digital inputs and outputs 5,0,4,13,12 as well as 2,4 (assuming no i2c spi use...)<br>
as well as the 1 volt limitedA0 pin?
2. The led pin on/off software rocks.. however i noticed it only works if im on the same network...How do I set it so that it will work from my work (or for that matter any remote) computer? Im assuming the "Posting to phant" combined with the Ap web server example of led on/off will allow one to do this.. and by one I not me... I tried mixing and matching the statement into the code but could never get it to compile...
ideas?</p>

According to all my research, if the unit is transmitting, it will give erroneous data on the ADC... I'm looking for numbers in the 50s, and it spikes 50% - 75% of the time to 430 of 1023. My research also tells me the radio transmit will goof the ADC cause it's used for something during transmit, so if you want to use the ADC you must put the radio in modem sleep mode... but that mode doesn't seem available in the arduino environment. Been able to get everything else working great with the hookup guide, but this one is driving me nuts.</p>

Looking at the <em>ESP8266 Thing - Dev board</em> , it was designed to keep the cost of the development board low and there were requests to keep the original ESP8266 Thing. The main differences are:</p><pre><code>1.) 2-pin JST connector
2.) LiPo charge circuitry
3.) built-in FTDI
4.) Trace for DTR and Debugging
</code></pre><p>The ESP8266 Thing Dev board does not have the 2-pin JST connector [ <a href="https://www.sparkfun.com/products/9749" rel="nofollow">https://www.sparkfun.com/products/9749</a> ] or the LiPo charge circuitry like the original ESP8266 Thing. We have a variety of chargers available on our storefront if you decide that you want to charge the LiPo without removing a LiPo battery from the ESP8266 Dev board => <a href="https://www.sparkfun.com/search/results?term=lipo+charger" rel="nofollow">https://www.sparkfun.com/search/results?term=lipo+charger</a> . The LiPoly Charger single cell [ <a href="https://www.sparkfun.com/products/12711" rel="nofollow">https://www.sparkfun.com/products/12711</a> ] is more flexible but it is a bit more expensive compared to the other LiPo chargers. This is due to the amount of components that are populated on the board.</p><p>The plus side is that there is a built in FTDI on the board to upload code to the board. Personally, I feel that this is a more reliable connection than using the external FTDI basic breakout based on my experience. The ESP8266 Thing Dev board does not include a trace to cut the DTR pin which makes it easier to debug and send serial data to a serial monitor/terminal. You would not need to cut any traces like the original ESP8266 Thing and constantly have to jump the pins when you need to upload.</p><p><strong>Upload Error Issues</strong></p><p>If you are seeing this error using the Thing:</p><pre><code>> warning: espcomm_sync failed
> error: espcomm_open failed
</code></pre><p>flip the power switch to OFF, press the upload button on Arduino with the correct settings for the Thing, and flip the power switch back to ON right before upload. You have to get the timing right in order to upload code.</p><p>Try looking at this other comment thread for other troubleshooting tips with that error => <a href="https://learn.sparkfun.com/tutorials/esp8266-thing-hookup-guide/discuss#comment-55a05571ce395f88538b4567" rel="nofollow">https://learn.sparkfun.com/tutorials/esp8266-thing-hookup-guide/discuss#comment-55a05571ce395f88538b4567</a> .</p></p>

We'll look into this more - it's worked for me on a few platforms (Mac and Windows 7,8), but hasn't been exhaustively tested.<p>If you've got the esp8266/arduino addon, select "Generic ESP8266 Module" as the board, then set the flash size to "4M", and that should work for the Thing.</p></p>

I attempted to install the ESP8266 Arduino addon as instructed in the hookup guide but received the following error:
"https://raw.githubusercontent.com/sparkfun/Arduino_Boards/esp8266/IDE_Board_Manager/package_sparkfun_index.json file signature verification failed. File ignored." This error occurs when I open the board manager.
I was able to successfully install a different addon as described at https://github.com/esp8266/arduino. This addon installed without incident, however it is unclear whether the Thing can be programmed using any of these modules.
Has anyone successfully installed the Sparkfun ESP8266 Thing addon as described in the hookup guide?
If not, can any of the modules provided by the ESP8266 Arduino github can be used to program the Thing?<p>Thanks.</p></p>

There are various tricks you could try to get it to work (use the smaller panel, use a zener shunt on the large panel), or you could use a <a href="https://www.sparkfun.com/products/12885" rel="nofollow">Sunny Buddy</a> solar charger instead.</p>

Then again there doesn't seem to be a public full datasheet for the ATECC108, given that it's ASFAIK a superset of the ATSH204(A), so would a ATSHA204 work just as well?</p>

Is it possible to connect the large solarpanel from sparkfun(5W) directly to the power input and let it charge the lipo during daytime and pull power from the lipo during nighttime? Or do i need a separate solarcharger circuit as well?</p>

Since you probably are only going to need it once or twice we figure we'd leave it off and let you use your own.</p>

It would be nice to have something sourced in the country though. I am aware that the chip might come from overseas, but sometimes the production quality of stuff from eBay (China) is not up to snuff or does not work at all.</p>

The Adafruit Huzzah board has one mounted atop a board with custom circuitry. I'm not familiar with FCC regulations so I"m not sure if their board would fit your needs but the module itself they use is certified. Sadly the module doesn't breakout all of the functionality of the ESP8266 but it does provide more than the 8-pin modules.</p>

I know this has been done via NodeMCU, but I don't know if it's possible via the Arduino IDE. A challenge may be how to store the credentials for reboots.</p>

I was just thinking when I saw the module, that a better board was needed. Something like the Pro Mini but based on the ESP8266. You must have read my mind. I especially like that you included the LiPo charger. This is just about perfect for a simple IoT solution.<p>Except I would have named it "Io". Then the shield-like boards that supply the Thing specific functions (sensors and such) could be "T"s. ;-)</p><p>Good job folks!</p></p>
