Charge battery Module (13.2 or M002) from Base26 (or else, not USB-C)
-
Hello all,
I have a CoreS3-SE (no internal battery), a Battery Module M002 (same bus connections as the 13.2) and a Base26 with power input barrel connector 9-24V.
I'd like to charge the battery when the sytem is powered from the Base26 connector (and not from the USB-C), possibly by doing some internal modification or an additional circuit. I have the whole Base26 customizable PCB for that. I'd prefer not to use the USB-C port.
The battery module should act as a kind of "UPS" for the system.
What's the best/most reliable way to do that?
Could the 4 pin connector on the back of the CoreS3 module, just over the USB-C port, be a good way to connect the +5V from the Base module? Seems a USB connector (D+ and D-) and, from schematics and indication on the back plane shield, should be a good place for GND VUSB (in practice identical to the USB-C port).Thank you!
