GPIO Expander HAT for ROCKPro64 and Quartz64
#7
Revision 2 soldered up and ready to be tested.

The new pin headers work well.

If anyone is interested in building one themselves, I've got a number of leftover PCBs, and if there's enough interest I'll put them on my Tindie shop with a BOM list for the components.

Update: tested and it works!
