@teastain2 Thank you Terry for taking some time to investigate!

Unfortunately the schematics are a bit above my head. Are there some pins or components on the board that you're recommending I test?

I should note that the device does not seem to recognize and charge the battery when it is installed. I am suspecting a hardware issue at this point, but would like to confirm.

@teastain2

I have not edited the firmware, the device is running v2.2.11 of the Meshtastic firmware.

Hello,

I've recently recieved a T-Beam Supreme (M) that will not power up when on batter power.

I've used the pins to check voltage, and I have

• 4.19v on VBAT to GND
• 0v VBUS to GND
• 0v VSYS to GND

My electronics knowledge is quite limited, are there further troubleshooting steps I can take to identify the issue?

Thank you in advance for any suggestions and assistance
