Elite C is an alternative to the Pro Micro microcontroller, used in DIY and/or split keyboards. Elite C pros over the Pro Micro:

  • Six more I/O pins (23 total) to work with than the Pro Micro, meaning more pins for extra experiments
  • A through hole mounted USB C port meaning it is less prone to breaking than the usb port of the Pro Micro
  • Preinstalled DFU bootloader providing additional protection when flashing

Improvements over Elite C v3:

  • Less bright power LED
  • Reset button is lower, because of the lower footprint of the USB port
  • Mid-mounted USB C port . Shaves off 1.2mm of vertical space, making it 25% thinner than the v3
  • VUSB pin is broken out, meaning it’s easier to make modifications that require the use of an external battery or power, like an external USB port, adding bluetooth etc


I tried flashing the Elite-C with the QMK Toolbox, but it won’t work. How can I fix that?
-> You probably need to install drivers, or update your existing ones. More info on that here: QMK documentation.

Can the Elite-C be used as the master and a Pro Micro as the slave, on a split keyboard ?
-> Yes. They are compatible with one another. Note that the Elite C comes with a different bootloader than the Pro Micro. Elite-C uses DFU and Pro Micro uses Catarina. That means when flashing you have to use: flash the Elite-C with :dfu, and the Pro Micro with :avrdude.
