There are a number of external PCB connectors for purchase 18 with an 80w 1.27mm pitch that can be used to easily access these extra pins. 19 20 Only the pins on the front are connected to signals. The back rings are 21 connected to the front rings, but the back small strips are unconnected. 22 23 Pin assignments can be found at: 24 https://tech.microbit.org/hardware/edgeconnector/#edge-connector-pins 25 26compatible: "microbit,edge-connector" 27 28include: [gpio-nexus.yaml, base.yaml] 29
