ELRS 915MHz TX Transmitter Back Module With V3 Antenna

The ELRS 915MHz TX Transmitter Module is a long-range radio control module designed for RC drones, fixed-wing aircraft, and FPV systems. It operates on the ExpressLRS (ELRS) protocol, which is an open-source, high-performance, and ultra-low latency control system widely adopted in the FPV community. Running at 915MHz ISM frequency, this module provides extended range, excellent penetration, and reliable signal transmission. It comes with a removable antenna for flexible positioning and improved signal strength.

Features:

1. Protocol: ExpressLRS (open-source, fast, low latency, long-range)
2. Frequency: 915MHz ISM band (suitable for most regions where 915MHz is legal)
3. Transmission Power: Adjustable (commonly 100mW – 1000mW depending on model)
4. Ultra-Low Latency: ~4-25ms depending on packet rate
5. Long Range Capability: Up to tens of kilometers with proper antenna setup
6. Antenna Included: High-gain detachable antenna for stable transmission
7. Compatibility: Works with radios that support JR or Nano module bays (depending on model type)
8. Firmware Upgradable: Can be updated via Wi-Fi or USB to keep up with the latest ELRS improvements
9. Cooling System: Some versions include a built-in cooling fan for stable performance at higher power levels
10. Lightweight & Compact: Easy to install and remove from the radio transmitter
11. Use Cases: FPV drones, RC planes, long-range UAVs, and robotics requiring reliable control
