ESP32 Forum

Howdy!

I bought an ESP32 device on AliExpress, but I'm having trouble programming it in the Arduino IDE. This is probably because I'm not sure which Board to select. I would really appreciate any help you ESP32 experts could give me in identifying my device and helping me program it in the Arduino IDE. I have attached a link to the AliExpress posting where I bought the device, plus two photos of the device. If you need any additional photos or information, please let me know.

Thanks,

A.J.

BTW, I have previously successfully programmed a LOLIN32 Lite board by selecting "WEMOS LOLIN32" as the board. This also shows that I have installed the ESP32 files correctly into the Arduino IDE.

Here is a link to the AliExpress posting where I bought the device:

I found a solution!

When uploading a sketch, when the "Connecting........" status is displayed, press and hold the IO0 button until the status changes. Then release the button, and the sketch should upload and run properly. I think this works because the push button forces the GPIO0 signal LOW, which is what it needs to be in order to put the device into Bootloader mode, in which it can accept a new program. Then when the button is released, the subsequent reset, with GPIO0 now HIGH, causes the device to execute the new program.

BTW, I was able to upload and run sketches successfully, with the Board set to either "WEMOS LOLIN32" or "Node32s". I think "Node32s" is the correct setting, as I believe this device is essentially the same as a NodeMCU-32S, so I don't think the Board setting is all that important, as long as it's set to some kind of ESP32 device.

Hope this helps someone else!

I had the same issue with one of my board.

I solved it by installing the proper driver for the chip. Sometimes using the windows default driver won't work.
