Overview
The BETAFPV Micro-Nano Module Adapter is a module adapter that lets a Nano TX module work on radio transmitters with a Micro port (or JR port). This upgraded version adds a 3Pin GH1.25 terminal socket for Futaba and other non-OpenTX radio controllers, and is designed for easy installation. It supports the BETAFPV ELRS Nano TX Module.
Key Features
- Converts JR module bay (Micro module bay) to Nano module bay (Lite module bay).
- 3Pin GH1.25 terminal socket added for Futaba and other non-OpenTX radio controllers.
- Wide compatibility across OpenTX and non-OpenTX radio transmitters.

Details

Convert a Micro/JR module bay to a Nano/Lite module bay for cleaner Nano TX module installs across more radios.

The upgraded adapter board adds a 3-pin GH1.25 terminal for Futaba and other non-OpenTX transmitters.

Designed to work with a wide range of radios, including popular OpenTX models and select non-OpenTX controllers.

Clear signal labeling helps verify the JR bay pinout before powering on, especially when using the PCBA without a case.

Use the GH1.25 connector for simple CRSF power and signal wiring on compatible transmitters.

Pair the adapter with supported Nano TX modules such as the BETAFPV ELRS Nano TX for a Nano-size external link.

Everything needed to mount and connect the adapter is included: the adapter, converter cable, and double-sided tape.
