They are in various colors, but the light blue or clear ones are great and the wate...

Re: USB descriptor request failed - [SOLVED]

Can you provide a link to the seller so we can avoid them ? Here it is, don't buy BluePills from this provider, unless you are ready to re-solder the USB connection lines: https://www.aliexpress.com/item/1pcs-STM32F103C8T6-ARM-STM32-Minimum-System-Development-Board-Module-For-arduino/32762695389.ht...
