the system reference manual has most of that info: https://github.com/beagleboard/beaglebone-black/wiki/System-Reference-Manual#battery-access-pads except that on black wireless's (at least on ours which have board id A335BNLT and version BWA5) they're labelled differently: tp2 BAT, tp3 SENSE, tp4 TEMP and tp5 GND you'll have to solder in connectors or headers for those four pins, but at least they're through-hole (not like on the bbb enhanced...). there's another small gotcha: neither wifi nor bluetooth are powered when you're on battery. see the discussion at https://electronics.stackexchange.com/a/373735 which, taken together with the schematics for the black wireless at https://github.com/beagleboard/beaglebone-black-wireless/blob/master/BeagleBone_Black_Wireless_SCH.pdf will tell you about diode d2 which is the cause for that and which is deliberately left unpopulated. besides that the builtin power supply magic offered by the TPS65217 pmic is lovely; we use this here with a supercap (and some passive components) as a little ups to shutdown safely on power loss. regards az -- Best Regards, Alexander Zangerl IT Engineer BREATHE-SAFE intelligent cabin air filtration Keeps your lungs and cabin dust free!
