Schematics available?

david

Is there a circuit diagram available for this board?

I have a few questions like:
Which GPIO pins are the USB data pins connected to (USB DP & DM)
Are there series resistors on the Tx and Rx lines (GPIO 44 & 42)
Exactly how is Supply Current and Battery Current measured. I'm having difficulty reconciling the values I get with measurements from external supply measurements.

Hi @david, here is the schematic:

As for the questions:

They are on GPIO19 & 20, as these are the USB pins for ESP32-S3
No, there are no series resistors on GPIO42 && 44.
The supply current and battery current measurement uses the measurements provided by the charger IC, the TI BQ25628E.
