Description

The RadioMaster Ranger Micro ELRS Module is engineered for pilots requiring maximum control link reliability and minimal latency. Its core is built around the SX1281 RF chipset, which operates in the 2.4GHz band (2400-2480 MHz) and is capable of dynamic packet rates, including the high-speed F-1000Hz mode for near-instantaneous control response. The module incorporates a dual-processor design with an ESP32 as the main MCU and an ESP8285 auxiliary chip dedicated to the ExpressLRS backpack functionality.

This design enables direct wireless configuration via WiFi or Bluetooth, eliminating the need for USB cables for firmware updates or Lua script adjustments. The module’s high-efficiency cooling system ensures stable operation during extended flights, while its wide 6V-16.8V input range provides direct compatibility with most modern transmitter battery configurations. The included T-antenna offers robust omnidirectional coverage, making it suitable for general FPV racing and freestyle applications.

Key Features

  • ExpressLRS Backpack Integration: Built-in ESP32/ESP8285 system enables wireless WiFi and Bluetooth connectivity for firmware updates and configuration without a USB cable.
  • High-Speed RF Core: Utilizes the SX1281 RF chip supporting the full ExpressLRS protocol suite, including dynamic packet rates up to 1000Hz for ultra-low latency control.
  • Robust Power Design: Accepts a wide input voltage range from 6V to 16.8V, ensuring compatibility with 2S, 3S, and 4S transmitter battery packs.
  • Optimized Thermal Management: Incorporates a high-efficiency cooling system to maintain consistent RF output power and processor performance during prolonged use.
  • Modular Antenna System: Comes with a T-antenna for general use; supports optional directional antennas like the MOXON for specialized long-range applications.
  • Compact Micro Connector: Specifically designed form factor with a Micro connector for seamless integration with RadioMaster's latest MkII series transmitters and other compatible radios.

Applications

  • Upgrading RadioMaster TX16S MkII, TX12 MkII, and other compatible EdgeTX transmitters with high-performance ExpressLRS control links.
  • FPV racing drones requiring the absolute lowest latency and highest refresh rates for competitive edge.
  • Long-range and cinematic FPV builds where reliable signal integrity and configurable telemetry are critical.
  • Multi-pilot environments (e.g., races, events) benefiting from the dynamic packet rate and frequency hopping capabilities of ExpressLRS.
  • Development and testing setups utilizing the integrated WiFi backpack for rapid firmware iteration and parameter adjustment.

Frequently Asked Questions

What transmitters is the RadioMaster Ranger Micro module compatible with?

The Ranger Micro module uses a Micro connector and is designed for direct compatibility with RadioMaster's TX16S MkII and TX12 MkII radios. It is also compatible with any other transmitter featuring a compatible external module bay (JR-style) that supports 6V-16.8V power and the ExpressLRS protocol via CRSF.

How do I configure the module and update its ExpressLRS firmware?

The module features a built-in ExpressLRS backpack with an ESP32 and ESP8285. You can connect to it via WiFi or Bluetooth using the ExpressLRS Configurator tool, allowing for wireless firmware updates and parameter changes without needing a USB cable. The process is initiated by putting the module into WiFi mode via the transmitter's Lua script.

What is the maximum RF output power and supported packet rate?

The module's default output power is 100mW, which is user-configurable via the ExpressLRS software. It supports the full range of ExpressLRS dynamic packet rates, including the high-performance F-1000Hz mode for the lowest possible control latency, ideal for competitive FPV racing.

Can I use a different antenna with the Ranger Micro module?

Yes. The module includes a T-antenna for omnidirectional coverage, but the RP-SMA connector allows you to attach other 2.4GHz antennas. For directional gain and extended range, you can use optional antennas like a MOXON or a high-gain patch antenna, which are beneficial for long-range flight applications.
