This Micro:bit and Adafruit CLUE connector breaks out the ports with an edge connector so you can use conductive materials to put circuits together on almost anything, nearly anywhere!
This board breakouts out majority of pins onboard the microcontrollers for greater capabilty and project versatility. Multiple powerpads make circuit building cleaner, and lower profile with less cross over. The design allows ample room for a wide array of connection types and conductive materials. This board's card reader is soldered on the front and backside using SMD and Through hole techniques making it durable and strong!
