M5Stack Core2 Battery / LoRa module

Hello all, I have a question about the M5Stack Core2… can you replace the battery in the unit? I’d like to try to get a higher capacity battery since it looks like the one Amazon sells has a 500mAh battery.

Also, second question, do you know if the COM.X LoRaWAN module would fit in the Core2?

Thanks!
Brian

Hello @brianbgarber and welcome to the RobotShop forum,

can you replace the battery in the unit?

No, but you can add the M5GO Battery Bottom2 extension board to upgrade the battery to one with 500mAh capacity.

do you know if the COM.X LoRaWAN module would fit in the Core2?

Yes, but please note that due to the different order of the base pin array, COM.X base pins TX(16), RX(17) correspond to the actual pins TX(14), RX of the Core2 main control (13). The equipment needs to use external DC for power supply.

Here’s a note from the manufacturer:

Note: When using the CORE2 or CORE2-FOR-AWS main control to drive the module, please use the DC power input of the base and set the power mode to input mode (refer to the code below), otherwise it will not start normally

//mbus_mode_t:
//kMBusModeOutput: Use USB or battery power
//kMBusModeInput: Use external power supply 5V, or DC interface

M5.begin(true, true, true, false, kMBusModeInput);

//Initialize Serial according to the actual connected pins
Serial2.begin(115200, SERIAL_8N1, 13, 14);

Great, thank you very much!
