This is the Sparkfun Format ProMini (A4-A7 in the middle) and it's used on the Morse Code Buzzer Controller, but will work in the cpNode-PM and BB-ProMini. The cpNode-PM and BB-PM can use the more common DFRobot format, which should be less expensive on various marketplaces. We can do programming for cpNodes and Morse Code Buzzer Controllers, contact us for a quote.
