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

The Mateksys CRSF-PWM-V10 is a compact protocol converter with an onboard variometer, translating digital CRSF receiver signals into standard PWM for servos and ESCs on fixed-wing gliders, scale aircraft and other builds without a full flight controller.

Key features

• 10 configurable PWM outputs, switchable between 50Hz (default), 100Hz, 160Hz, 330Hz and 400Hz update rates for analog or high-speed digital servos.
• Onboard barometer streams live altitude and climb-rate (variometer) telemetry back to the radio, alongside RxBt, current, capacity, battery %, GPS and heading.
• Works with any CRSF-protocol receiver - TBS Crossfire, ExpressLRS or Tracer - on 433MHz, 868MHz, 915MHz or 2.4GHz.
• Direct Vbat sensing up to 36V (8S LiPo) and a 0-3.3V input for an external current sensor, both with configurable scaling.
• Compact 38 x 16mm PCB weighing just 1.8g fits narrow glider fuselages and tight equipment bays.

Specifications

• Protocol: CRSF to PWM

• PWM Update Frequencies: 50/100/160/330/400Hz
• Vario/baro telemetry: requires EdgeTX 2.7.1 / OpenTX 2.3.15 and ExpressLRS 2.5 or newer
• Dimensions: 38 x 16mm
• Weight: 1.8g
• In the box: 1x CRSF-PWM-V10, 2.54 mm Dupont pins

Configuration and firmware updates run through the Matek-Configurator tool over USB-to-UART; cross the receiver's TX/RX lines with the converter's UART pads for a reliable telemetry link.
