  • ——————– Tech Support Tips/Troubleshooting/Common Issues ——————–

    If you ever need to reload the original Blynk firmware to your board:

    • Download the this file from Github that contains the core firmware plus the Blynk board Eagle files.

    • Unzip that file, and in Arduino, navigate to the BlynkBoard_Core_Firmware folder in the file you unzipped.

    • Open the BlynkBoard_Core_Firmware.ino file in Arduino. You should see several other tabs open besides the main sketch.

    • Click upload and you should be good to go!

    Note: It takes a long time to compile. This was tested in Arduino 1.6.6.

  • Nope, that’s intentional. Check the Assembly Tips section of the hookup guide for more information on why we designed the board this way.

  • Hello and thanks for asking! This product is not discontinued at this time. We’re simply out of one of the parts needed to assemble it and don’t have an estimate of when that part will arrive. Once we have that part back in stock, we will make more PTJs.

  • The copper itself can probably handle around 5 amps, but it’s going to heat up carrying that much. Possibly more heat than you might consider acceptable. The conductive adhesive on the other hand likely won’t be able to pass more than a few hundred mA. I’m afraid that this tape likely would not do well in an application like this.

  • Hi and thanks for asking! I just tested one of these and with a 2.4 amp load, the voltage comes out to 5.03 volts. The reason for the difference between this supply and the older one is this supply has thicker wires that have a lower resistance allowing you to use have a 5 volt output at full load.

  • How to use the logging capability on the Venus GPS Logger.

    First, you must use the SkyTraq software we have on this product page.

    • 1) Connect a LiPo battery to the JST connector, OR an external 3.3 volt regulated DC power supply. (Don’t use a 3.3 volt FTDI breakout for power, it can’t supply enough current. The Beefy 3 will work for both power and data though.)

    • 2) Download and install the SkyTraq 0.4.833 software from this product page.

    • 3) Connect a 3.3 volt FTDI breakout (or other 3.3 volt USB to serial converter.) to the GND, RX and TX pins on the Venus GPS.

    • 4) Start the SkyTraq software, select the COM port your FTDI breakout is on. Set the baud rate for 115200 and then click the “Connect” button. You should start seeing NMEA data scroll by in the message window.

    • 5) Go to the “DataLog” menu at the top of your screen and select “Log Configure.” Change any options you want to. I find that the defaults work well.

    • 6) At the bottom of the Log Configure Control window, select “Enable” for the “DataLog:” option, then click the button labeled “Settings”You should see “Log Configure Control Successful” appear in the Response window.

    • 7) If you want to start with a fresh empty log, go back to the “DataLog” menu and select “Log Clear.” You should see “Log Clear Control Successful” in the Response window.

    • 8) At this point, your Venus is logging data to it’s onboard memory. Take the GPS with you on a nice hike, or a short drive around the block. To retrieve that data follow the next steps.

    • 9) Reconnect your Venus to a computer with a FTDI cable like you did before, then follow step 4 to get SkyTraq ready to download new data.

    • 10) Go to the “DataLog” menu and select “Log Read Batch.” The software will prompt you to save the accumulated data to a file on your computer. Click save to do that.

    • 11) At this point, you have downloaded a compressed version of your stored GPS data to your computer. In order to convert that to use able data, you need to do one more step.

    • 12) To convert that data file, go back to the “DataLog” menu and select “Log Decompess.” The SkyTraq software will ask for the file you just downloaded. Select that file, then click on save. A window saying “Decompress is completed!” should appear. Click OK.

    • 13) In the same folder you downloaded the GPS data, you will now find three new files. a .logg file that contains human readable positional data, a .nmea file that has NMEA GPS data in it, and a .kml file that can be loaded up in Google earth showing your journey.

  • We don’t, but any standard ATX power supply should work. You can find then in an old computer or at a computer store.

  • Position is a rough estimate provided by the Iridium satellite, not an absolute GPS position. It should be around a kilometer of the actual position though. In Nick’s case, it looks like the Iridium coordinates are about 1.4km north west of Nick’s actual position. You could always include GPS coordinates in your message if you needed more accuracy but even without GPS, this is pretty accurate.

    I’ve not read all the technical documents for this product yet so I don’t know if you can query it for position. I suspect you would need to initiate a data transfer to do so but I could be wrong. As cheap as GPS has become, ($16!) it would be easier to just use that if you need accurate position fixes.

  • Close, but no cigar. The information on this page will get you on track. :-)
