I’m just tinning the leads into the screw terminals.
I love and hate terminating wire, it’s fun but super time consuming.
All of the power and board interconnects are in place. Just need to build power connectors.
This package has:
M4 express feather
3 bidirectional level shifters, slow speed mostly for i2c and shifting 3.3v control signals to 5v
Sparkfun differential i2c
Bme280 (barometric pressure is what I want from it)
256kb i2c fram, a place for fan profiles and whatever else
I2c, the m4, and level shifters are on UPS, M4 takes over basic feeding if the power goes out
