{"product_id":"matek-crsf-to-6ch-pwm-converter-crsf-pwm-6","title":"Matek CRSF To 6CH PWM Converter (CRSF-PWM-6)","description":"\u003cp\u003eThis product will be useful for people requiring PWM outputs from their ExpressLRS or Crossfire radio receiver. It converts from CRSF, which is the protocol used by ExpressLRS and Crossfire receivers, to PWM outputs which is the signal used to drive servos and ESCs. This particular breakout board provides 6 PWM connections and PWM output frequency can be adjusted for faster servos (50Hz default, 100, 160, 330, 400Hz) – if you need more connections, Matek make a 10-channel version which also includes on board current sensor. In addition to the PWM connections, the board provides 2x uarts to allow for connection of a GPS receiver (NMEA output), which then transmits the coordinates along with the Crossfire Telemetry. The board is compatible with up to 36v input, but please note this doesn’t power the servo rail, instead you should power from an external source e.g. a 5v ESC UBEC or external voltage regulator .\u003c\/p\u003e\n\u003cp\u003ePlease note, this listing is just for the converter and doesn’t include a receiver as pictured in the images below.\u003c\/p\u003e\n\u003cp\u003ePinouts and Pads\u003c\/p\u003e\n\u003cp\u003eTx1\/Rx1(UART1) for CRSF protocol Receiver\u003c\/p\u003e\n\u003cp\u003eTx2\/Rx2(UART2) for GPS\/firmware update\/setting parameters\u003c\/p\u003e\n\u003cp\u003e1~10: CH1~CH10 PWM outputs\u003c\/p\u003e\n\u003cp\u003eCurr: current sensor signal (0~3.3V)\u003c\/p\u003e\n\u003cp\u003eVbat: Battery voltage sensing (0~36V)\u003c\/p\u003e\n\u003cp\u003eG: ground\u003c\/p\u003e\n\u003cp\u003e4v5 pad voltage = 5V pad voltage -0.3V, make sure the voltage on 5V pad is not higher than receiver and GPS rated voltage.\u003c\/p\u003e\n\u003cp\u003eFailsafe\u003c\/p\u003e\n\u003cp\u003eFailsafe value is set automatically after CRSF-PWM board is powered on and receive CRSF signal.
