STARDRONE Ranger Micro 2.4GHz ELRS Module for RadioMaster Transmitters — Works with TX16S, TX15, TX12 & More

Upgrade Your RadioMaster Setup with the STARDRONE Ranger Micro ELRS Module

The STARDRONE Ranger Micro is a compact, plug‑in upgrade designed to unlock the efficiency and flexibility of the ELRS protocol on your existing RadioMaster radios. Powered by the SX1281IMLTRT RF chip and an ESP32 MCU, this module aims to deliver stable performance across a range of RC applications without requiring new hardware.

Designed to fit JR‑style micro module bays, it slots into RadioMaster ELRS transmitters—such as TX16S, TX16S MkII, TX15MAX, TX15, TX12, TX12 MkII, and similar radios. If you use Nano connectors, consider Ranger or Ranger Nano modules crafted for those ports. This thoughtful compatibility keeps your investment streamlined while expanding capabilities.

Key Benefits at a Glance

• Core ELRS experience: 2.4GHz ELRS protocol powered by the SX1281IMLTRT RF chip and an ESP32 MCU for steady operation.
• JR‑style compatibility: easy integration with RadioMaster ELRS transmitters and related radios; Nano connectors may require alternative modules.
• Cooling for reliability: an efficient cooling system helps manage heat during high‑load use and maintain consistent performance.

Connectivity, Speed, and Ease of Use

Built‑in WiFi and Bluetooth simplify setup and ongoing monitoring. Firmware updates can be completed over WiFi, and parameter configuration becomes more flexible when paired with mobile devices.

• WiFi for quick firmware updates and parameter adjustments
• Bluetooth for effortless device pairing and live status checks
• Maximum packet rate up to F‑1000Hz for highly responsive control (EdgeTX 2.7.1+ required)

The module supports up to a 1000 Hz packet rate while remaining compatible with receivers that refresh at a minimum of 25 Hz, allowing you to tailor performance to your ELRS transmitter and flying style.

What’s in the Box

Each package includes 1 x RadioMaster Ranger Micro 2.4GHz ELRS Module and 1 x T‑shape antenna, optimized to maximize signal coverage and ease of installation.

Real‑World Use and Considerations

In practical terms, this module is geared toward higher‑demand RC sessions, from rapid FPV racing to steady long‑range testing. The combination of robust chipset, cooling efficiency, and flexible connectivity is designed to support a broad range of setups, without promising specific outcomes. Users can expect smoother control and configurable telemetry paths, with performance shaped by their individual gear and settings.

Why Players Might Choose Ranger Micro

• Maintain a familiar transmitter ecosystem while expanding ELRS capabilities
• Benefit from improved heat management during extended sessions
• Leverage WiFi and Bluetooth for convenient updates and device pairing
