USB Dongle ELRS for Wireless FPV Sim Connection
Connect to your computer and play FPV sims wirelessly with this USB dongle. It has a built in ELRS receiver as well as solder pads for connecting your own CRSF compatible receiver such as a Crossfire receiver. You can plug it into USB-C or USB-A. If you add your own CRSF receiver to the module, you can switch between the added receiver and the inbuilt ELRS receiver using the switch on the side.

Firmware: HGLRC_Hermes_2400_RX

Updating Firmware
1. Use the ELRS Configurator to download the desired Hex file for the dongle (HGLRC_Hermes_2400_RX)
2. Plug the dongle into the USB Port. Wait for the red light on the BOTTOM of the unit to flash fast.
3. On your computer (or phone) connect to the dongle when it shows up in the wireless access point list.
4. Update the firmware as you would for any ELRS receiver.

Binding
1. Plug and unplug the dongle to the USB port. It will go into bind mode no previously bound Rx is detected. Or you can plug it in to power it up 3 times in quick succession. This will put the onboard ELRS receiver into bind mode.
2. In your TX menu bind to the dongle the same way you would bind to any other ELRS receiver.

Crossfire Receiver Support
There are solder pads for a receiver to be added inside the case. You can add any CRSF compatible receiver such as a TBS Crossfire receiver. Solder the receiver to the pads on the board the same way you would solder to a flight controller TX to Rx and Rx to TX. Then move the switch to the USB-A end to select the external freceiver. Note that you may need to cut a hole in the case for the antenna to protrude.
