This SMT edge connector for use with the BBC Micro:Bit has only 40 pins so it is lighter and easier to fit. The bottom side of the Microbit is not connected to anything.
The edge connector has 40 pins on the top side at 1.27mm pitch, which translates to the 20 "actual" pins on the Micro:Bit

This edge connector has posts at either end to locate it correctly into the PCB
