I’ve just bought the MicroPython Programming Book and reading about flashing MicroPython to the ESP32Huzzah board. This board does not have a BOOT/FLASH button like the older boards. Is this going to present a problem, as I don’t want to brick the card.
I don’t think it will be an issue.
With the huzzah you probably don’t need to press the BOOT/FLASH button to upload code.
However, I’ve never used a ESP32 huzzah, but I don’t think that’s a problem.
Thanks Sara. I think the board is a fairly recent release. I will try flashing it and report progress to this thread for others to see.
Hi Sarah, here is how it went.
The ESP32 Huzzah board differs somewhat to earlier ESP32 boards. It does not have a BOOT/FLASH switch and the pinouts are different. You do nat need to worry that the boot switch is missing, it is no longer required.
I could not get it to work with UPyCraft so flashed the firmware with esptool.py, which worked first time.
For your next revision of MicroPython_Programming with ESP32, you should note that where on earlier boards pin 2 was connected to the onboard LED, on this board it is pin 13, so users will have to change that to get the blinking LED example to work.
Thanks for pointing that out. I don’t have an huzzah, so I didn’t know it used another pin for the LED. But I’ll make sure to include some information about that on the next eBook update.
I’ll mark this question as resolved. If you need further help, you just need to open a new question in our forum.
Might be worth looking up, but I think you will find quite a few, or maybe even all the pins on the Huzzah are different.
