ERROR wile connecting micropython to esp32 port

Post by OrangePython » Fri May 20, 2022 9:09 pm

when I try to connect my esp32 card to Thonny IDE for micro python an error is displayed telling me that your port does not exist as a result after
some research I was able to install the driver 'CH341SER.EXE'
then another error is displayed:

Unable to connect to COM6: port not found

Backend terminated or disconnected. Use 'Stop/Restart' to restart.

by going to device manager I found a new port installed called USB-Enhanced-SERIAL CH9012 (COM6) but it appeared with a yellow label

I tried something else but it didn't work

what will I do in this case? :geek: :roll:

The yellow label might indicate the ch340 malfunctioned. Most usual cause is low voltage, eliminate any inline USB ammeters, try a thicker USB cable.
