TBS Crossfire

Overview

TBS Crossfire is a long-range RC link from Team BlackSheep. It commonly uses the 868 MHz or 915 MHz band and sends receiver data to the flight controller using CRSF.

Pros And Cons

Pros Cons
Mature long-range system More expensive than many alternatives
Strong telemetry support Larger antennas than 2.4 GHz systems
Reliable CRSF integration with Betaflight Usually needs an external transmitter module
Good for long range and penetration Not as tiny as some ELRS receiver options

Betaflight Connection

Crossfire receivers usually use a full UART:

1
2
3
4
Crossfire CH1 TX -> Flight controller RX
Crossfire CH2 RX -> Flight controller TX
5V -> 5V
GND -> GND

  • Receiver protocol: CRSF.

See CRSF Protocol for the serial frame structure, message types, and device addresses used by Crossfire-compatible receivers.
