Re: can I bypass the CP2102 chip on the NANO with an FTDI based serial adapter? #nano #arduino #cp2102 #ftdi

You should be able to connect your FTDI cable directly to the D0 and D1 pins on the Nano. The onboard chip drives the serial data through 1K resistors and allows the D0 and D1 pins to override the onboard chip. You may need to manually press the reset button before starting a new program upload.
