Coming soon - CH552 QT Py is a tiny 8051 board
We designed this CH552-based QT Py board before the chip shortage, but now parts are plentiful so we made some prototypes and are trying out the CH55xduino (https://github.com/DeqingSun/ch55xduino) board support package. and, it works! but watch out, its C not C++ so you can't use the huge collection of existing libraries and drivers. however, for about '40 cents' per chip, you get a 8051 with native USB that can do CDC/HID, has 4x 8-bit ADCs, hardware serial, I2C, SPI and doesn't need a crystal or a lot of passives. obviously there's down sides to such a minimal 8-bit microcontroller chip…
