I recently purchased an M5Stamp Pico and a USB to TTL converter from Amazon. The converter uses the CP2102 chip. I connected the 3.3v, TX, RX, and ground pins, and shorted the ground to G0. However, Windows does not recognize the USB board. I have attempted to download various drivers for the CP2102 chip, but none have resolved the issue. Can someone please give some advice to get the board to function?

Hey after a while for a new one to come in that seems to be the case, but now I seem to be running into a new error.

WARNING: Failed to communicate with the flash chip, read/write operations will fail. Try checking the chip connections or removing any other hardware connected to IOs.
Configuring flash size...

and I have reinstalled the drivers almost 10 times at this point. I tried it on different computers and also trying different operating systems. I also tried different ports on those computers.

It looks like your TTL adapter is not working.
