SpeedPuck Firmware

Instructions:

To change the firmware on a new SpeedPuck (model year 2021 and up):

  1. Connect the SpeedPuck to a computer.
  2. It will behave like a thumb drive (or any other USB mass storage device).
  3. Open the SpeedPuck, and then open the Firmware folder.
  4. Remove the existing .hex from the Firmware folder.
  5. Drag and drop the new .hex firmware file into the folder.
  6. Unplug your SpeedPuck from the computer.
  7. Turn your SpeedPuck off and then back on again.
  8. Wait for a moment for the firmware update to begin.
  9. You will know the firmware is updating when the SpeedPuck counts from 0 to 100 on screen.
  10. When it hits 100, the update is complete and the SpeedPuck will begin operating normally, using the new firmware.

Note: You do not need to open a .hex file or assign a default program to open a .hex file to change the firmware on your SpeedPuck.
