GEPRC RX as TX JR-Bay Modification Kit

Summary

The GEPRC RX as TX JR-Bay Modification Kit is a quick and easy DIY solution that takes advantage of the ELRS receiver’s ability to upgrade via firmware into a TX module.

This kit is compatible with a variety of controllers that have a JR bay, and the 3D-printed version features a vibrant, multi-colored shell. It supports 2-6S input voltage and 5V@1A output, ensuring stable power. With three connection options for the receiver and a custom mount designed specifically for GEPRC receivers, installation is hassle-free. The dual-antenna design converts the receiver into a Gemini TX module, while the optional cooling fan ensures smooth operation. Paired with 915M/2.4G dual-frequency T-type antennas, it allows for seamless frequency band switching.
