Overview
The FrSky TW R10 is a TWIN series receiver using the stable TW protocol with simultaneous working dual active 2.4GHz frequency bands (active-active). It is designed for RC users who want resilient radio communication and long-range performance, and it features triple 2.4GHz antennas with IPEX1 connectors.
TW R10 provides configurable channel ports that can be assigned as PWM, SBUS, FBUS, or S.Port. When set to FBUS in the ETHOS system, signal control and telemetry can be connected to compatible devices through a single line for bidirectional transmission and reduced wiring complexity.
Key Features
- Simultaneous Working Dual 2.4G TW Mode (dual active 2.4GHz frequency bands)
- Basic black-box data record function
- Long control range (range varies based on the RF power settings)
- 10 configurable channel ports
- FBUS / S.Port support
- SBUS Out port (supports 16CH / 24CH mode)
- SBUS In port (supports signal redundancy)
- Over-the-Air (OTA) firmware update
