Overview
The FrSky TWIN Lite Pro is an RF module designed for ETHOS-capable radios, enabling binding to FrSky TW series receivers and supporting the TW protocol’s dual 2.4G frequencies simultaneously on the same receiver. The TW active-active protocol keeps dual 2.4G frequency bands active on the module and receiver at the same time (not an active-standby redundancy system).
With two external 2.4G antennas, the module provides multi-directional coverage and wider signal transmission compared to single-antenna designs. It also supports ACCST D16 and ACCESS modes for broader receiver compatibility, and offers adjustable RF power up to 500mW in a CNC-machined metal shell to aid heat dissipation.
Key Features
- Supports TW / ACCESS / ACCST D16 RF protocols
- TW mode for ETHOS radios: dual 2.4G signals working simultaneously (active-active)
- Low-latency: <4ms, supporting full telemetry (TW mode)
- Long-range control: tens of kilometers (range varies based on RF power settings)
- Adjustable RF power: 10mW / 25mW / 100mW / 200mW / 500mW
- CNC-machined metal module shell designed to aid heat dissipation
- Dual external 2.4G antennas for wider coverage
