Radiomaster Bandit ELRS Micro TX 915MHz 1W External Module — Radio Module for Transmitters
The Radiomaster Bandit Micro ExpressLRS (915MHz, 1W) is a compact and powerful external radio module from the Radiomaster brand, designed to significantly extend the control range of drones and other UAVs. The module operates on the modern ExpressLRS protocol in the 915/868 MHz regulatory domains and provides an output power of up to 1W (1000mW / 30dBm) with support for high-frequency packet transmission up to 200Hz (minimum 25Hz), ensuring stable communication even at long distances.
The device features a high-contrast OLED display and a convenient five-way navigation button for intuitive parameter setup without the need for computer connection. A Type-C port is provided for connection and updates. The Bandit Micro also supports Wi-Fi and Bluetooth, has a built-in ExpressLRS "Backpack" function, and can interact with additional modules or be used as an ESP backpack thanks to the auxiliary ESP8285 microcontroller. The main microcontroller is ESP32, and the radio chip is SEMTECH SX1276.
Advantages and Features
- Compatible with transmitters featuring a micro (JR) bay, such as TX16S MKII, Boxer, TX12 MKII, and other models;
- High output power up to 1W (1000mW / 30dBm) for extended range;
- Packet refresh rate up to 200Hz, minimum 25Hz, ensuring fast telemetry and control transmission;
- Low operating noise and optimized energy-saving circuit;
- Active convection cooling for stable operation under prolonged load;
- OLED display and five-way button for quick setup directly on the module;
- Wi-Fi and Bluetooth support for firmware updates and remote control;
- Built-in ExpressLRS "Backpack" function for extended use scenarios.
Compatibility and Antennas
The Bandit Micro is designed for transmitters with a micro (JR) bay. The kit includes a universal RadioMaster T-antenna, suitable for most tasks. For directional communication over very long distances, a RadioMaster Moxon antenna can be purchased separately, allowing the configuration to be adapted for amateur or professional needs.
