Receiver Port

Also called FlexiIO. This port can be used to interface with the RC receiver using PWM or PPM protocols, some pins can also be used for Led outputs, Motor outputs or DTR pin for OSD programming.

Multiple combinations are possible: PWM, PPM, PPM+PWM, PPM+Outputs, PPM+Telemetry, PPM+DebugConsole, PPM+ComBridge, PPM+MSP, PPM+MAVLink, PPM+GPS, Outputs, Telemetry, DebugConsole, ComBridge, MSP, MAVLink or GPS.

Serial function can be used with Telemetry or DebugConsole, ComBridge, MSP, MAVLink, GPS.

Flexi Port

Can be disabled, or connected to one of the following::Telemetry, GPS, TelemetryI2C, I2CDSM, OsdHkEX.Bus, DSMHoTT, SRXL or a Debug Console, IBus, DebugConsole, ComBridge, MSP or MAVLink.

Main Port

Can also be left disabled, or connected to telemetryto Telemetry, GPS, S.Bus, DSM or a Debug Console, DebugConsole, MSP or MAVLink.

With DSM, this means the flight controller can work directly with a Spektrum satellite receiver.

Warning
titleVoltage input

Any sensor can be used as long as the input voltage to Revo's Sensor Port pins does not exceed 3.3V. Higher values can damage board's CPU!
Normal Revolution board has ESD chips that prevent for over voltage.
