Description

The RadioMaster Ranger Nano 2.4GHz ELRS Module integrates a high-performance SX1281 RF chipset with a dual-processor architecture, utilizing an ESP32 as the main controller for the ExpressLRS protocol and an ESP8285 auxiliary processor dedicated to the Wi-Fi and Bluetooth backpack functionality. This design allows for seamless wireless firmware flashing and real-time tuning without physical connections. The module’s advanced thermal management, featuring a high-efficiency cooling system, maintains optimal operating temperatures even at maximum output power, ensuring consistent RF performance and longevity.

Engineered for the Nano form factor, it provides a direct upgrade path for compatible transmitters, delivering the long-range, high-packet-rate benefits of the ExpressLRS ecosystem in a compact package. The inclusion of a T-shaped antenna offers omnidirectional signal coverage, while the design supports optional directional antennas like the MOXON for specialized applications requiring extended range or interference rejection.

Key Features

  • Dual-Processor Architecture: Combines an ESP32 main MCU for ELRS flight control with a dedicated ESP8285 for Wi-Fi/Bluetooth backpack services, enabling concurrent operation.
  • SX1281 LoRa RF Chip: Delivers robust 2.4GHz signal penetration and long-range performance with high interference immunity, ideal for crowded RF environments.
  • Wide Voltage Input (6V-16.8V): Powered via XT30 connector, supporting direct connection to 2S, 3S, or 4S LiPo packs for field use without a transmitter's internal battery.
  • High-Efficiency Active Cooling: Integrated thermal management system prevents thermal throttling, ensuring sustained high-power output during prolonged use.
  • Nano Bay Compatibility: Compact form factor (136mm x 42mm) designed specifically for transmitters with Nano-sized module slots, such as the RadioMaster Zorro.
  • Integrated Configuration Backpack: Built-in Wi-Fi and Bluetooth allow for easy firmware updates, Lua script adjustments, and real-time telemetry monitoring via smartphone or computer.

Applications

  • Upgrading compatible Nano-bay transmitters (e.g., RadioMaster Zorro) for long-range, low-latency FPV drone control via ExpressLRS 2.4GHz.
  • High-speed racing and freestyle FPV builds requiring the ultra-responsive F-1000Hz packet rate for precise maneuverability.
  • Long-range cinematic or mapping drone setups where reliable control link integrity at extended distances is critical.
  • FPV pilots operating in RF-congested areas (e.g., events, urban environments) benefiting from the LoRa-based signal robustness of ExpressLRS.

Frequently Asked Questions

What transmitters is the Ranger Nano module compatible with?

The Ranger Nano is specifically designed for transmitters with a Nano-sized module bay. It is directly compatible with the RadioMaster Zorro. It is not compatible with standard JR-style or Micro module bays; for those, you would need the Ranger or Ranger Micro models respectively.

How do I update the firmware or configure the Ranger Nano module?

The module features a built-in ESP32 Wi-Fi and Bluetooth backpack. You can connect to it via Wi-Fi using a web browser or use Bluetooth with the ExpressLRS Lua script or configurator on your transmitter or computer for wireless firmware updates and real-time parameter adjustments without any physical cables.

What is the power input requirement for the Ranger Nano module?

The module is powered via an XT30 connector and accepts a wide voltage range of 6V to 16.8V DC. This allows it to be powered directly from a 2S (7.4V), 3S (11.1V), or 4S (14.8V) LiPo battery, providing flexibility for field use independent of your transmitter's internal battery.

What antenna is included, and can I use a different one?

The package includes a T-shaped omnidirectional antenna designed for general-purpose, all-around signal coverage. The module's antenna connector is standard, allowing you to use optional antennas, such as a directional MOXON antenna, to increase range or focus signal strength in a specific direction for specialized applications.

Package Includes

  • 1 x Ranger Nano Module
  • 1 x T Antenna
