Are you looking for a compact and great value Arduino-compatible to embed in your projects? Or you just want a really cheap board? Then check out this Arduino Pro Mini compatible board. It uses the ATmega328P microcontroller and runs the Arduino bootloader. Furthermore it has an extra two analogue inputs pins - not found on the DIP version. Awesome!
This is the 5V 16 MHz version. Header pins are supplied loose for you to solder on if necessary. Equivalent to Sparkfun DEV-11113. Click here for the 3.3V 8MHz version.
Includes a 12 month Tronixlabs hardware warranty, so why pay more anywhere else? Full specifications can be found on the Arduino website. If you need a matching USB interface adaptor or cable, check out our range of adaptors.
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 (5V 16 MHz)", as shown below:
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, as shown below:
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.
