Description

The RadioMaster Bandit ExpressLRS 915MHz RF Module is a professional-grade transceiver engineered for critical low-latency communication in radio-controlled aviation and drone systems. Its architecture combines the processing power of an ESP32 with the long-range, interference-resistant modulation of a SEMTECH SX1276 LoRa chip, optimized for the ExpressLRS protocol to deliver packet rates from 25Hz to 200Hz. This enables rock-solid control links with minimal latency, essential for FPV racing and long-range UAV operations.

Beyond its RF performance, the module is built for operational durability and user convenience. The machined aluminum enclosure provides superior heat dissipation for the 1W power amplifier, while the integrated OLED screen and tactile navigation interface allow pilots to configure binding, power output, packet rate, and model settings directly in the field. The inclusion of both omnidirectional and directional antennas offers immediate adaptability for various flight profiles, from acrobatic proximity flying to long-distance exploration.

Key Features

  • Ultra-low-latency ExpressLRS protocol support with dynamic packet rates up to 200Hz for real-time control.
  • High-efficiency 1W RF power amplifier with built-in TCXO oscillator for stable frequency generation and improved range.
  • Dual-processor design: ESP32 handles main logic and WiFi/Bluetooth, ESP8285 manages the dedicated ExpressLRS backpack.
  • Rugged CNC-machined aluminum housing acts as an integrated heat sink and provides robust physical protection.
  • On-module user interface with OLED display, directional nav key, and programmable shortcut buttons for standalone configuration.
  • Includes comprehensive accessory kit: T Antenna, Moxon Antenna, Micro/Nano adapters, UART & Futaba CRSF cables, and mounting hardware.
  • Optimized circuitry and power management for low overall consumption during high-performance operation.
  • Built-in accelerometer for potential motion-based triggering or advanced telemetry features.

Applications

  • First-Person View (FPV) Drone Racing & Freestyle for ultra-low-latency control links.
  • Long-Range UAV & Drone Operations requiring robust telemetry and command links.
  • RC Plane & Helicopter Control Systems upgrading to high-performance digital radio links.
  • Custom Ground Control Stations (GCS) and telemetry hubs leveraging WiFi/Bluetooth connectivity.
  • Professional Cinematography Drones where reliable control signal integrity is critical.

Frequently Asked Questions

How do I flash or update the ExpressLRS firmware on the Bandit module?

Connect the Bandit module to your computer via the included UART cable. Use the ExpressLRS Configurator web tool or the ExpressLRS Lua script via an EdgeTX/OpenTX radio. The module's dual-MCU design allows you to update the main ESP32 firmware via WiFi or serial, and the ESP8285 backpack firmware via the configurator. Ensure you select the correct target (Radiomaster_Bandit_900) and your desired packet rate and regulatory domain (FCC/CE) before flashing.

What is the purpose of the two included antennas, and when should I use each?

The T antenna is an omnidirectional dipole, ideal for general flying where the aircraft's orientation changes rapidly, such as in FPV racing or acrobatics. The Moxon antenna is a directional, gain-optimized antenna. Use it for long-range flights where you can point it towards the aircraft, as it provides a stronger signal in its focused forward direction but has nulls to the sides and rear. Always ensure the antenna is securely connected before powering the module.

Can I use this 915MHz Bandit module in a region where 868MHz is the standard?

Yes, the module and the included Moxon antenna are specified as 915/868MHz compatible. You must configure the firmware for the correct regulatory domain (e.g., CE for 868MHz EU) in the ExpressLRS configurator, which will set the appropriate frequency limits and power output caps. Using 915MHz hardware on 868MHz may slightly reduce optimal antenna efficiency, but operation is fully supported within the SX1276 chip's frequency range.

How do I connect the Bandit module to my radio transmitter?

The module uses standard JR-style bay connectors. Use the included Micro or Nano adapter to fit your transmitter's module bay. For telemetry and configuration via CRSF (Crossfire Serial Protocol), connect the included Futaba CRSF cable between the module's 4-pin port and your radio's appropriate serial port. For firmware updates or direct serial configuration, use the included UART cable to connect to a computer's USB port via a serial adapter.
