Smaller versions of the board as per original design are with 0.56" and 0.8"
Software / Firmware
As the board in essence is a module with ATmega328 it requires firmware to
run it as per original design can be found at Sparkfun
Github
repository.
Optionally the firmware can be modified to build a custom application.
