Follow instruction on waveshare web site. I really wish it had mounting holes and had all the unused pins available still. Also the extension needs to have a read value option so you dont have to code re-code every key to slave other operations to keys. I think might be able to in Java, but I can only use blocks. Over all not bad touch keys trigger better than expected, very sensitive.
Does not work with V2 of the microbit, nor do any of the other brands of this device. Untill someone figures it out this is a dead product.
