The booby-trapped DevTerm GPIO

NOTE: my experience is with the R-01 module, but since the mainboard remains the same regardless, this will apply to all available brains. I wanted to add an RTC to my DevTerm. This is something that has been quite simple on my other SBC based devices. I knew it would be a challenge with this one because of the unconventional connector employed. I went to Adafruti looking for a suitable break out kit but didn’t find what I wanted. So I went over to new egg and found the parts: break out PCBs, t…

How expandable is the GPIO pin set for CM4? What good accesories and connectors are out there?

J3 - 40 pin FPC header GPIO 0 - 27 all clockwork cards us pins 0-5, and 8-11 to control the power, headphones, backlight, etc. the remainder of these pins, 6-7 and 12-27 are not connected on the CM4 module. MINI_PCIE - Ext Module GPIO 28 - 45, Camera Pins, 2x USB, Speaker L/R all of these pins are connected to the CM4 and A06, but using them requires a custom ext module board that will expose them. Note these pin numbers are the common clockworkpi notation, they don’t map 1:1 with the CM4 p…
