GEPRC LINKFLOW Dual-Band TX Module — 915MHz/2.4GHz, 1000mW, ELRS
The GEPRC LINKFLOW 915M/2.4G Dual-Band TX Module is a next-generation ExpressLRS transmitter module built on the Semtech LR1121 third-generation RF chip, supporting 868/915MHz and 2.4GHz dual-band operation in a standard JR bay form factor. With up to 1000mW output power, a TCXO for temperature-stable frequency accuracy, an active cooling fan, and an integrated ESP32-C3 backpack chip, the LINKFLOW delivers professional-grade long-range FPV control with maximum flexibility.
Key Features
- Semtech LR1121 RF Chip — Third-generation chip supporting 868/915MHz (LoRa) and 2.4GHz (ISM) dual-band operation
- 1000mW Max Output Power — Maximum transmission power for long-range FPV operations
- TCXO Oscillator — Temperature-compensated crystal oscillator minimizes frequency drift for stable long-term performance
- Active Cooling Fan — Adjustable-speed fan for efficient heat dissipation during high-power transmission
- ESP32-C3 Backpack Chip — Enables peripheral integration and expanded functionality
- Reserved UART Port — Configurable as a communication repeater or high-power receiver
- JR Bay Form Factor — Standard module bay compatible with JR-bay transmitters
- 2–6S External Power (XT30) — Wide voltage input for flexible power options
- WiFi & USB Firmware Updates — Easy OTA or wired firmware upgrades
- RGB LED Status Indicators — Clear visual system status feedback
- 50Hz–500Hz LoRa / 1000Hz FSK Refresh Rate — Flexible packet rate for range vs. latency optimization
