I want my homemade arduino to communicate with my PC. Do I need a max32 chip in this diagram?
I have max232 chips & DB9 socket pair in my inventory. So I want to make some useful things out of it.
I already have a bafo converter, so serial to usb is no an issue.
some usb serial breakout boards have RST, some have RTS, some have DTS pinout along with Tx, Rx, Vcc, GND... Which one should I buy..?
