From now and then, we fix bugs in the Omnixie and post the latest firmware to this site. Now if you are comfortable, you can update the firmware by your self. The latest version is v1.3.7 as of July 6th, 2019.

Omnixie and Omnixie Plus share the exact same firmwares and flashing procedure.

What you’ll need for the update:

  1. a USB-to-Serial adapter (those with CP210x chip are recommended)
  2. Four pieces of jumper wires.
  3. 2mm hex allen wrench
