Overview:
The Matek CRSF 10 channel breakout/converter board is designed to accept a CRSF signal and allow 10 PWM (e.g servos, ESC) devices to be connected. This board also includes on on board Barometer for use as a Variometer for gliders. The board features configurable PWM frequency output, external current sensor input and failsafe. The board also features 2x uarts to allow for connection of a GPS receiver (NMEA output), which then transmits the coordinates along with the CRSF Telemetry. The board includes a small 5V regulator on board to power GPS and the externally connected receiver. Servos etc need to be powered by an external BEC.

GPS telemetry
Compatible with GPS NMEA protocol
GPS “TX” to CRSF-PWM board “RX” Single wire half duplex UART connection, CRSF-PWM board “TX” to GPS “RX” is not essential.
Support GPS Telemetry ID: GPS, GSpd, Hdg, Alt, Sats
u-blox series GPS can output “0+1 – UBX+NMEA” protocol by default
Sensors(GPS, GSpd, Hdg, Alt, Sats) will blink in Transmitter TELEMETRY tab once CRSF-PWM board has connection with GPS.
Troubleshooting for no GPS telemetry, double check the wiring between GPS and CRSF-PWM board, some u-blox GPS may don’t output NMEA protcol, you need to be reverted GPS to default configuration in u-center.
with OpenTX Telemetry Logging, You can plot your flight path or search the lost plane.
VSpd telemetry (Vario)
VSpd telemetry is supported by ExpressLRS 2.0, EDGE 2.6, OPENTX 2.2 or newer.
support barometer MS5611(I2C address 0x77) and SPL06-001 (I2C address 0x76)
Includes:
- 1x Matek CRSF-PWM-V10 - 10 Channel CRSF breakout with Variometer (Unsoldered)
- Dupont Pins
