Making DIY keyboard with CH551G programmed using Arduino IDE (CH55xduino)
For years, ATMega32u4 based boards, especially the Pro Micro has been my choice for USB projects that require more than just USB-to-Serial conversion, like simple keyboard projects. It has been simple solution for creating custom keyboards programmed with Arduino IDE.
Recently I have used CH551G in few projects and now I noticed that there is "CH55xduino" which brings decent support for it in the Arduino IDE. I had to test it to see if CH551G could replace ATMega32u4 in my simple projects... Answer is "Yes", it works wonderfully.
