Description

RadioMaster Ranger Nano is a compact external RF transmitter module that brings ExpressLRS 2.4GHz to your control radio without having to buy a new transmitter. Simply fit the module into the Nano bay (Nano slot) of a compatible radio and you get a modern RF link with fast response, stable telemetry and confident long-range performance. The module is designed for FPV, airplanes, wings and any applications where reliability and minimal control latency matter.

Ranger Nano supports high packet update rates — standard modes up to 500Hz, plus F-1000Hz for maximum stick responsiveness and razor-sharp control (requires EdgeTX 2.7.1 or newer). For quick servicing and setup, it includes Wi‑Fi and Bluetooth: update firmware, change parameters and connect without extra cables. Power is supplied via XT30 over a wide 6–16.8V range, making it convenient for different sources — from 2S to 4S.

The kit includes a T-shaped antenna that provides solid coverage for everyday flying. If you need a directional link for specific scenarios, the module is also compatible with the optional MOXON antenna. Inside is a proven platform based on ESP32 (main controller) and ESP8285 (ESP backpack) paired with the SX1281 RF chip, while thoughtful cooling helps maintain stability even under prolonged load. Ranger Nano is a simple way to make your control system modern, fast and durable.
