Hi,

I purchased the Keybow Mini a few years ago, but only recently assembled it.

Minikeys 00 and 01 are working as expected, however minikey 02 is not working.

I’m using a Pi Zero W. The LEDs for all 3 keys are working and I have been able to change the colors on all 3 keys.

I tried changing the switches around as a test (to determine if one of the switches is defective), but all 3 switches seem fine.

The problem is always with minikey 02, and none of the mini code key examples work with this key. The other two minikeys work with all the other code examples.

Any ideas?

Thanks in advance of the support!

Update: I tried a different Pi Zero W board and all 3 keys worked this time. So the issue I’m encountering is likely a problem with the header on my other board. It has a hammer-in header so there may be a connection issue.

Pinout is here, if that helps.  
[Keybow Mini at Raspberry Pi GPIO Pinout](https://pinout.xyz/pinout/keybow_mini#)  
Key 3 is GPIO 6, physical pin number 31.
