MATEKSYS CRSF-PWM Converter with Variometer CRSF-PWM-V10

The Mateksys CRSF-PWM-V10 is a dedicated 10-channel protocol converter with an onboard variometer, designed to translate digital CRSF receiver signals into standard PWM output for servos and ESCs. Ideal for fixed-wing gliders, scale aircraft, and custom builds that operate without a full flight controller, it connects modern TBS Crossfire, ExpressLRS (ELRS), or Tracer receivers directly to standard R/C hardware.

Key features

• 10 Configurable PWM Outputs: Delivers ten individual servo channels with adjustable update frequencies (from 50Hz up to 400Hz) tailored for both standard analog and high-speed digital servos.
• Integrated Barometer & Variometer: Features an onboard SPL06-001 high-precision pressure sensor that streams real-time altitude and vertical climb rate data directly back to your radio transmitter via telemetry.
• Wide Telemetry Expansion: Includes dedicated Vbat pads for direct battery voltage sensing up to 36V (8S LiPo), plus onboard UART connections to interface external GPS modules or current sensors.
• Direct CRSF Compatibility: Plug-and-play operation with any receiver outputting the standard CRSF serial protocol, eliminating the need for complex signal conversion adapters.
• Compact & Lightweight: Weighing just 3.4 grams and measuring 38mm x 16mm, the PCB fits comfortably into narrow glider fuselages and tight equipment bays.
