4× PWM / DSHOT over CAN
Four independent servo outputs (GND, VS, PWM) driven over UAVCAN / DroneCAN — no signal wires back to the autopilot.
Power & Servo
ServoNode x4
SKU · AAD-SERVONODE-X4 · CAN SRV x4E
A CAN-connected node that powers and controls servos and ESCs over the bus — isolating the load from the flight controller. Four independent PWM outputs plus a separate ESC control output with telemetry, immune to EM noise and ready to expand the controller's PWM channel count.
Key Advantage
Powers and controls servos and ESCs over CAN — the load is isolated from the controller, immune to EM noise, plus PWM output expansion.
Highlights
Core specs and the CAN-bus advantages that set ServoNode x4 apart.
- 4× PWM / ESC + telemetry
- up to 34V (8S)
- 5V/8V · 4A
- 7 g
ESC Output + Telemetry
A separate ESC control output (GND, TELEM, PWM) supporting PWM or DSHOT, with motor telemetry returned over the bus.
Load Isolated From the FC
Servo and ESC loads sit on the node, not the controller — a servo fault never reaches the flight controller.
EM-Noise Immunity
Moving control onto the differential CAN bus keeps actuator switching noise off the autopilot's sensitive lines.

Frequently Asked Questions
How does ServoNode x4 protect the flight controller?
It powers and controls four servos plus an ESC over DroneCAN and isolates the load from the controller — so a servo short or stall (up to 34 V / 8S, selectable 5V/8V output) never reaches the autopilot.
What is ServoNode x4 compatible with?
ServoNode x4 is built to run as one system on the AAD stack — it pairs with BattleCore FC7, PowerRail 14S, PowerCore EX and CAN PMU 16S.
How does ServoNode x4 connect?
It connects via CAN — DroneCAN (dual connectors) to the flight controller; 4× servo outputs (GND, VS, PWM); ESC output with telemetry (GND, TELEM, PWM); PWM or DSHOT.
What's included in the box?
1× ServoNode x4 node. Full box contents are detailed in the Knowledge Base.
Is ServoNode x4 NDAA-compliant and made in the USA?
Yes — ServoNode x4 is NDAA-compliant and made in the USA.
