The Happymodel EP82 VRX Backpack Module is designed to allow wireless communication between ExpressLRS, and other FPV-related devices for command and control, or for querying config. A small ESP-based receiver can be “piggybacked” onto your VRX module, which allows ExpressLRS to control the band and channel that your goggles are set to. We call this device the “VRX-Backpack”.
