Neturona Wand Bench Testing Firmware:

If you wish to test (or use) the Neutrona Wand without a Proton Pack, download and flash the Neutrona Wand Bench Test Firmware to your GPStar Neutrona Wand board. This will allow the Neutrona Wand to operate without waiting for a response from the Proton Pack. This is useful for debugging whether the serial connection is incorrect and preventing things from starting up or to test the Neutrona Wand.

Please note: The Neutrona Wand will not attempt to connect to your Proton Pack if you are running the bench test firmware.
