ISM2400 Ranger ELRS Module

RANGER Product Information

The RANGER is a high-performance radio control system that is designed to offer long-range communication with your aircraft. The product features a rugged CNC case with an efficient cooling system, OLED display, Wifi and Bluetooth support, built-in accelerometer, directional Nav key, and customizable shortcut buttons. The RANGER also offers a power output of up to 1 watt, and it comes with a Futaba CRSF cable included. It is important to note that packet rates over 500Hz require EdgeTX 2.7.1 or later for optimal performance. The RANGER features an ISM2400 regulatory domain, ESP32 (main) and ESP8285 (aux) MCU, and SX1281IMLTRT RF chip. It supports a frequency range of 2400 MHz to 2480 MHz and has a maximum receiver refresh rate of 500Hz/F-1000Hz. The RANGER also comes with built-in RGB lights, an OLED screen, G-sensor support, and XT30 power supply voltage of DC 6V ~ 16.8V. The product weighs 155 grams (with antenna) and measures 905124mm in dimension.

How to Update Firmware

To update the firmware on your RANGER, follow the instructions provided in the user manual.

How and When to Use Your Moxon or T-Antenna

The Moxon directional antenna is intended for long-range communication and has a more narrow field of operation. Keep the Moxon antenna pointed in the general direction of your aircraft. The T-Antenna is an omnidirectional antenna that is suitable for short to medium-range communication and most conditions. Both antennas support vertical/horizontal polarization.

How to Use Futaba CRSF Cable

To use the Futaba CRSF cable, ensure that your Futaba radio firmware supports CRSF function. Follow the instructions provided in the Futaba manual to select the servo test port to CRSF. Connect the RANGER via CRSF cable and connect a XT30 2s-3s lipo battery to the RANGER.

Important Regulatory Information

The RANGER complies with FCC radiation exposure limits for an uncontrolled environment. The product should be installed and operated with a minimum distance of 20cm between the radiator and your body.
