Universal Flight Sim I/O

One Node.
Every Peripheral.

The PRD-NODE is a universal CAN peripheral node that powers any flight simulator peripheral — throttle quadrants, trim wheels, flaps levers, radio panels — over a shared CAN bus network using standard Ethernet cables.

Why PRD-NODE

Everything you need, nothing you don't

Designed specifically for flight simulator builders who want professional results without reinventing the wheel for every peripheral.

🔌

Universal Node

One board serves every peripheral role. Wire up encoders, pots, servos, and switches via plug-in breakout boards — trim wheel, flaps lever, throttle quadrant, radio panel.

Bridge Built-In

Need a CAN-USB bridge? Populate the USB connector and barrel jack on any PRD-NODE. It automatically becomes the bridge when VBUS is detected — no separate hardware needed.

📡

CAN Bus Network

All nodes connect over CAN bus using standard Ethernet patch cables with a custom RJ45 pinout. One USB connection to the PC controls the entire rig at 500kbps.

🧩

Breakout Board System

The PRD-NODE ecosystem includes dedicated breakout boards for each application — TrimFlaps, Axes, Switches, Radio, Servo — so there's always a board that fits your build.

🖥️

SPI2 Display Port

A dedicated 2×3 SPI2 header exposes MOSI, MISO, SCK and CS — ready for SSD1322 or SSD1306 OLEDs and any SPI peripheral, without taking header pins away from I/O.

🔧

Open Development

Built on STM32CubeIDE with HAL drivers. STDC14 debug header on prototypes. DFU bootloader always available via USB. Firmware examples and documentation freely available.

How it works

From boards to cockpit in four steps

Order your boards

Buy PRD-NODE boards and the breakout boards for your peripheral devices. One NODE per instrument or control group.

Wire your peripherals

Connect pots, encoders, switches, and servos to the breakout boards using 3.5mm pluggable screw terminals.

Flash and connect

Upload firmware via USB DFU. Connect boards via Ethernet cables. Power the rig from the bridge NODE's barrel jack.

Fly

One USB to PC. SimLinkHub connects to MSFS. All controls work immediately as CAN peripheral nodes.

The Ecosystem

Boards for every instrument

Every product in the range maps to something cockpit builders recognise — not signal types, but real controls and instruments.
