Happymodel Fyujon V2.0 2IN1 Module built in ELRS 2.4GHz EP receiver and OpenVTX

ELRS Fyujon is a very simple and easy-to-use 2-in-1 module that integrates 5.8GHz video  transmission and 2.4GHz ELRS receiver.

They can be integrated into a board for use, or they can be split into independent VTX modules and receiver modules for you to be used separately.

The Module is a open source solution, used by a growing FPV community.

Compatible with 20mmx20mm, 30mmx30mm stack mounted positions and 25.5mmx25.5mm whoop mounted position.

Due to the ultra light weight (only2.1gram), it would be a great choice for your toothpick builds or a analogue Cinewhoop.

Special thanks  to  Sushmit Mishra for the design improvement

More Information

The ELRS RX and OPENVTX share the same Power input and GND pads, so if you use both ELRS RX and VTX then just need solder one Power input and GND.
