PWM Output from FMU (J28)¶
This connector provides the PWM outputs from the FMU. The EchoPilot AI's autopilot hardware consist of a main processor (FMU) and an IO processor. The IO processor provides 8 PWM outputs (labeled IO CHX below) and the FMU provides 4 PWM outputs. An important distinction between the two is that only the FMU outputs are D-Shot compatible.
The +VServo Sense input is optional and is used by the FMU to detect a drop in the VServo rail. The EchoPilot AI has a 2:1 voltage divider onboard to protect input of up to 6.6V (3.3V * 2). This is an input only, the Carrier board does not provide power to the servo voltage rail.
The EchoPilot AI comes with a PWM Breakout board which allows users to use standard Futaba-style (3 pin, 0.1" spacing) servo connectors. The PWM Breakout Board is plugged into this connector with the supplied cable.
