How To Make A CH340 USB-To-Serial Adapter Work With An ATMega328 Breadboard


A few months ago I took an interest in the ATMega328 and Arduino so I built a small project that used a breadboard style configuration, but on a perf-board. The project worked well so I decided to build something else, but thought I would like to have a USB-to-Serial adapter too. In my previous project I used a TinyUSB programmer which I modified with a cable from my junk box to allow it to plug onto the ISP header that I copied from my Arduino Uno.

The finished board appears here:
