Arduino Pro Mini 328 - 5V/16MHz
sku: DEV-09218
Description: It's blue! It's thin (0.8mm)! It's the Arduino Pro Mini! SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader (select 'Arduino Duemilanove w/ 328' within the Arduino software). Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Duemilanove. It's a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of system voltage (5V), lack of connectors, and USB off board.We really wanted to minimize the cost of an Arduino. The Arduino Pro Mini is like the Arduino Mini (same pin out) but to keep the cost low, we used all SMD components, made it two layer, etc. This board connects directly to the FTDI Basic Breakout board and supports auto-reset. The Arduino Pro Mini also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work.

If you would like to tell us more, you can fill out our form if you need some psycho-suggestive questions. Go to the form.




























- Configure your software for the USB development board if you haven't already.
- Remove the ATmega IC from USB development board (use an IC remover tool to avoid bending the pins).
- Connect 5v, GND, RESET, TX and RX from this device to the matching connections on the USB development board.
- Upload program.
- When finished, carefully plug the ATmega IC you took off earlier back in to the USB development board.
Both the v10 on the arduino site and the v11 eagle files here are wrong compared to the actual cards I received. Are the reference files or my boards outdated?

That's for the onboard LDO Regulator (If you're using the "RAW" pin for 5-12V DC Input. If you're feeding VCC directly, I'm assuming you can do more. The recommended limit for each pin is 20mA at 5V, along with the IC limits below:
From the ATmega328P Datasheet [p.305]:
"1] The sum of all [Current on High Outputs], for ports C0 - C5, D0- D4, should not exceed 150 mA."
C0-C5 are the ADC Ports marked on the board as A0-A3 and the unmarked A4 and A5.
D0-D4 are marked as RXI, TX0, D2, D3, and D4 respectively.
"2] The sum of all [Current on High Outputs], for ports B0 - B5, D5 - D7, XTAL1, XTAL2 should not exceed 150 mA."
B0-B5 are D8, D9, D10, MOSI, MISO and SCK.
D5-D7 are D5, D6, and D7.
Hope this helps clear things up a bit.
Yes.
You can see my adaptor here.

The first time it failed I couldn't access it via ISP but the second time it failed I could still program/verify etc.
I'm planning to get a couple more when they are back in stock and use them for different applications - hopefully the new batch will be better.

I should mention I also had a pro-328 fail with similar symptoms while others have been rock solid asis the USB aurduino. All the boards that failed were fairly early versions.
