Hi, please advise which micropython download I should use for the duinotech ESP32 Main Board from Jaycar Electronics.
Thank you in advance.

Both ESP32 firmware variants should work. But if the module has no SPIRAM, the non-SPIRAM version works better. You can use the daily build. They are well tested.

Assuming it's this board -- https://www.jaycar.com.au/esp32-main-bo ... n/p/XC3800 -- then it's a WROOM module, so no SPIRAM. From MicroPython's perspective, this is a "generic" module.

I would recommend the v1.13 release -- http://micropython.org/resources/firmwa ... -v1.13.bin
Or as Robert says, the current nightly build -- http://micropython.org/resources/firmwa ... 95682e.bin

Hi, Thank you for your responses, I have obtained the Generic ESP32 v1.13.bin. When I try to upload it to my board using the uPyCraft IDE with burn address 0x1000 selected Erase Flash gets to 47% before I get an Erase False error. I have tried various combinations of holding down the boot button / press and release the RST button while the erase flash starts but I always get the erase false error. I can not see what I can be doing wrong.
