Add a PCB air temp sensor. #61

Closed skot closed 10 months ago

skot commented 1 year ago

Because of #59 we're going to need a new way too measure (or approximate) chip temperature. This probably means adding a PCB air temp sensor as close to the ASIC and heatsink as possible.

a digital I2C temp sensor with the TMP75 is the most straight forward, but if there is a significant cost difference an analog temp sensor could work. We have plenty of ESP32 analog pins available.

the BM1366 has no internal temp sensor. @benjamin-wilson moved the EMC2101 up nice and close to the ASIC and I think that's working pretty well.
