How to Install

  1. Connect a USB-C cable into your computer’s USB port.  The included USB-C cable is ideal.  If not using the included cable, make sure the cable is not a power-only cable and has data lines, most cords included for devices that only need charging (flashlights, earbuds, etc.) don’t include data lines. Cell phones, USB hubs, any cable that came with device needing more than just power will have them.

    2. Turn off the LUMO if it is on

    3.  Hold down the button nearest the USB-C port

    4. With your other hand, insert the USB-C cable into the meter’s USB port. Keep holding the button until a storage device appears on your computer.

    5.    The first time, your computer may install some drivers.  The meter will appear as a USB storage device named “RPI-RP2”

    6.    Copy and paste the “.uf2” firmware file that you received from Reveni Labs onto the device

    7.    Agree to any prompts about copying the file

    8.    The meter will self-eject from the computer once complete

    9.    Once transfer is complete, disconnect the USB-C port from the meter

    10.    Enter the Settings Menu and confirm the version number at the top of the screen is now updated.
