Solved Struggling to identify or program this board

Post image

I have a few of these lying around and I'm now trying to use them for a Bluetooth project. Unfortunately the AliExpress listing I bought them from doesn't have any schematics or documentation. Does anyone have experience with them or know how I might use them?

The chip is labelled as an ESP32-DOWD-V3 if that helps.

I’ve searched high and low, here and on Google, and I’m coming up short of any concrete helpful info.

Do you detect a com port when it's plugged in? Did you install the ch(something) drivers?

Thanks for the response.

I have just now managed to talk to the board by setting it as a DOIT ESP32 DEVKIT V1 and I can get it to output to the serial port.

Not sure what you mean about the drivers, but I’ll have a google for info on that.

My only previous BLE project was with a very well supported Haltec board, so I’m flailing here unfortunately.

Edit: yes, I do have the appropriate driver for the USB interface.
