The Matek Systems CRSF-PWM-C is a robust Crossfire-to-PWM converter designed specifically for use with any CRSF protocol receiver, including TBS Crossfire models operating at 433MHz, 868MHz, 915MHz, or 2.4GHz. It features 10 independent PWM outputs, making it suitable for complex fixed-wing or traditional RC aircraft builds that require multiple servo channels. The CRSF-PWM-C includes a built-in current sensor capable of measuring up to 90A continuous (220A peak), and it supports battery voltage sensing up to 36V, providing comprehensive telemetry data such as current, voltage, capacity, GPS, and more directly to your transmitter. The device offers two UART ports for receiver and GPS connectivity, configurable PWM frequencies (50Hz by default, with options up to 400Hz), and automatic failsafe value setting for each channel. Firmware upgrades and configuration are supported via CLI mode and the Matek Configurator. Note that the CRSF-PWM-C does not have a built-in 5V regulator, so servos must be powered by an external 5V source. Its compact 26mm x 26mm form factor and versatile telemetry support make it an excellent choice for pilots seeking advanced control and monitoring without a traditional flight controller
