Compact ELRS Module for RadioMaster Ranger

The Ranger Micro 2.4GHz ELRS Module, developed by RadioMaster, offers an excellent solution for those seeking to experience the efficiency, long range, and low latency of the ELRS protocol without the need to purchase a new radio. Featuring up to 1W of output power, F-1000Hz refresh rates, and a high-efficiency cooling system, this module represents the cutting edge of ELRS technology.

Designed for compatibility, the Ranger Micro can be attached to a variety of radios, including the TX16S, TX16S MKII, TX12, and TX12 MKII, allowing users to enjoy the full benefits of the ELRS protocol. The included T-shape antenna is optimized for maximum signal coverage, while an optional MOXON antenna is available for directional applications.

It's important to note that the Ranger Micro 2.4GHz ELRS Module is compatible with JR-style micro module bays. For those with Nano connectors, the Ranger and Ranger Nano modules may be more suitable. Further information on the Ranger series can be found by clicking the provided link.

The Ranger Micro Combo package offers an ideal starting point for those new to the world of ExpressLRS. This package includes a complete Ranger Micro module, two RP1 ExpressLRS receivers, and one RP2 ExpressLRS receiver, providing a comprehensive solution.

Key features of the Ranger Micro 2.4GHz ELRS Module include:

★ High-efficiency cooling system ★ Up to 1 Watt of power output ★ Wi-Fi and Bluetooth support ★ Packet rates up to F-1000Hz ★ T-antenna included ★ Support for TX16S MKII and TX12 MKII radios with the Micro connector ★ Combo Package includes 1 x Ranger Micro Module, 2 x RP1 Receiver, and 1 x RP2 Receiver

Specification-wise, the Ranger Micro Module operates in the ISM2400 regulatory domain, with an MCU comprising an ESP32 (main) and an ESP8285 (auxiliary, acting as an ESP backpack). The RF chip is the SX1281IMLTRT, and the frequency range spans from 2400 MHz to 2480 MHz.

The maximum packet rate is 500Hz or F1000Hz (the F1000 mode requires EdgeTX 2.7.1 or later), with a minimum receiver refresh rate of 25Hz. The RF output power is 30dBm for FCC and 20dBm for CE, which can be adjusted via LUA. Both Wi-Fi and Bluetooth support are included.

The power supply voltage range is DC 6V - 16.8V, and the weight is 50g with the antenna or 40.5g without. The dimensions are 1364933mm with the T-antenna and 744933mm without the antenna.

It's important to note that the ELRS (standard) is pre-installed with the ExpressLRS ISM FW, and the maximum power is hardware-dependent.
