he Happymodel ELRS Fyujon is a very simple and easy-to-use 2-in-1 module that integrates 5.8GHz video transmission and a 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. These components are all open-source solutions that are currently very popular with FPV pilots. Compatible with 16mmx16mm, 20mmx20mm stack mounted way, and 25.5mmx25.5mm whoop mounted way. Due to the ultra-lightweight (only2.1gram), this board is a great choice for small toothpick quads or analog version Cinewhoops.
