RadioMaster Bandit 915mHZ ExpressLRS RF Module Radio Signal Transmitter — a high-performance radio module from the Radiomaster brand, developed in collaboration with the ExpressLRS team for use in UAVs, drones, and long-range radio communication systems. This module combines a reliable hardware platform with modern protocols, ensuring stable communication, high output power, and ergonomic solutions for professional pilots and enthusiasts.

Key Features

• Robust Design: The CNC-machined aluminum casing also serves as a heatsink for efficient heat dissipation and maintaining a stable operating temperature of the module.
• Control and Interface: The built-in OLED display and five-way navigation button allow for quick parameter setup and real-time monitoring of communication status directly from the transmitter.
• Antenna Options: The kit includes two antennas — an omnidirectional T-antenna for short and medium distances and a directional Moxon antenna for long-range flights.
• Technology Support: The module supports Wi-Fi and Bluetooth for convenient connection and diagnostics, while the integrated TCXO generator enhances operating frequency stability.
• Energy Efficiency: The optimized hardware design ensures low power consumption, extending the system's operating time without recharging during flights.
