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.

M.2 Connector for Cellular Modem (J30)¶
This is a Key B M.2 connector for use with a 3052 form factor cellular modem, such as the Sierra Wireless EM9191. The connector includes USB3.1 connectivity to the modem ( PCIe is not supported). Attach the modem using a M2x0.4mm x 3mm wafer head screw.
A heat pad under the modem provides the option for a heat sinking solution from the cellular modem. The following components can be used to build a heat sink:
Thermal Pad between the modem and Carrier Board: Panasonic EYG-T7070A15A (cut to fit):
14x14mm heatsink mounted on the Carrier Board: CUI HSB03-141406
Heatsink Adhesive: MG Chemicals 8329TFF-25ML
Connector: J29, Part Number: SM3ZS067U310ABR1200
Mating Connector: M.2 Key B Modem, size 3052
