Arduino Pro Mini-compatible with Expansion Headers - 3.3V
Now available from PMD Way is this useful version of a Pro Mini-compatible board with free delivery. It uses a larger PCB format which allows for rapid connection of various devices, as shown with the sets of inline header pins - easily connect three-wire dupont cables, etc., directly to I/O ports.
Note that this is a 3.3 V board.
A USB interface is not on the board, you can use a USBasp or an FTDI-compatible board for connection to a PC. An LED is connected to digital pin D13.
Using your Pro Mini with the Arduino IDE.
You will need to change the board and processor type in the Arduino IDE usin the Tools menu.
Set the board type to "Arduino Pro or Pro Mini" and the Processor to "ATmega328 (3.3V 8 MHz)".
The best way to upload a sketch to your Pro Mini is with an FTDI breakout board and USB cable. Then ensure the pins are aligned correctly with the FTDI board - match GND with GND on the FTDI board and you're set.
If you haven't soldered the six programming pins to your Pro Mini (or don't want to) then insert the pins into the FTDI breakout board, then place the Pro Mini over the pins. Be sure to hold the board firmly against the pins to ensure a good electrical connection while uploading the sketch.
If you receive the following error in the Arduino IDE during the upload process -
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00
... the connection between the FTDI breakout board and your Pro Mini isn't right. Check the pin alignment and firmness - then try again.
