# Programming
|
|
|
|
Plug the micro-USB port on the edge of td-io into a computer. It will appear as a USB flash drive. Drag and drop the firmware U2F file onto the flash drive. When programming is complete, the drive will disconnect automatically.
|
|
|
|
Once programmed, the white button must be held when plugging in the USB cable to re-enter programming mode.

# Basic test

2. Measure the pins on the JVS power connector and make sure the +3.3V line measures between 3.27V and 3.39V.
|
|
|
|
3. Ensure the volume pot turns smoothly and is not loose.
|
|
