 Oh, yeah, that's the product pick of the week right there, the CP2102N Friend. It's a USB to serial breakout conversion board. Lady Aida said, why don't you build a breadboard Arduino? In order to program this, this is plugged in over USB-C and then transmit and receive to the Arduino. To upload this, I have Arduino configured to think it's sending out to a due millenove, but it's actually sending USB to my CP2102N Friend, which is then sending over serial to the chip here to program it. So I'll hit upload in Arduino and then I'll hit reset once it starts to upload that helps it. And you'll see it very quickly flashes the board. It's already done. And now my LED is blinking at that sort of one second rate. The CP2102N Friend USB to Serial Converter.
