Product Details

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 to be used separately. They are all open source solutions that are currently very popular with FPV pilots. Compatible with 20mmx20mm, 30mmx30mm stack mounted way and 25.5mmx25.5mm whoop mounted way. Due to the ultra light weight (only2.1gram), it would be a better choice for small toothpick quad or analog version Cinewhoop.

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.
