PCB needed Revisions
- debug documentation should should show all TP pads, and not be the mirror image.
FET
- populate coin charger as default with 6.3V target voltage (R=1.21meg)
- way to measure coin cell voltage without charger enabled? MTR ENABLED -> disable 6V LDO
- change D13 to diode that actually has 200mV drop @ 1uA. BAS116-F-7 appears to have 427mV @ 0.3uA
SCMC
- populate so local vbat is default (R222, R233 installed)
- locate IMU header for easy access. possibly rot180 - or move 2mm away from edge.
- remove 1.25mm headers for EC30, replace with single 12x0.8mm header. add 3.3V to 5V level shift output.
- need to determine the accuracy of the RTC. Seems to be drifting.
IMU
- probably want to upgrade dual axis IMU
- battery measurement circuit needs to be re-done.
