Flashing the PCB to VIA

If your PCB does not support VIA, you can install the supported firmware yourself if you have a Windows or Mac PC.

Step 1

Download QMK Toolbox

Please note the system requirements.

Step 2

Install QMK Toolbox to your PC.

Step 3

After you have installed QMK Toolbox, ensure the QMK drivers have also been installed.

  1. Right click the QMK Toolbox app icon and and then right click on the qmk_toolbox and select Run as Administrator
  2. Select Install Drivers

Step 5

You can flash pcb as long have access to access the bottom of your pcb.

Step 6

  1. Ensure QMK Toolbox is running and plug in one of the PCBs with a USB-C cable to your PC that has QMK Toolbox running.
  2. In QMK Toolbox, select the Local file as the VIA firmware you previously downloaded. It will be in hex format and named something similar to “vitamins_included_rev2_via.hex”
  3. Ensure that “ATmega32U4” is selected as the MCU

Step 7

On the bottom of the PCB locate and press the reset button. This will put the PCB into boot-loader mode.

QMK Toolbox should then display in yellow, “Atmel DFU device connected”

If it displays the above you are ready to flash the PCB. If it does not, please check the previous steps.

Step 8

Click the “Flash” button

It will then take a few seconds and your PCB should now be flashed. You can now unplug the PCB and repeat from Step 5 for the other PCB. You must flash both PCBs to use VIA and its functionality.

Step 9

Once both PCBs have been flashed, you can now go to the VIA website and configure your preferences.

Click the Authorize device button and select the "Vitamins included" keyboard.

VIA only works on browsers that support WebHID API.
