Synapse PDM

Introductory Production Release

Synapse PDM is a 14-channel, open-source automotive Power Distribution Module designed for custom vehicles, motorsport, and advanced electrical systems. Developed and validated over multiple hardware iterations.

This initial production release is aimed at technically competent users who need a configurable, software-defined power distribution platform with integrated CAN bus telemetry and control.

See the wiki for full documentation and hardware details.

Why Choose Synapse PDM

• Flexible and Configurable: Each input and output is fully programmable to suit a wide range of applications, from replacing conventional automotive fuse and relay systems to managing complex distributed electrical architectures. Multiple Synapse PDM units can be deployed on the same CAN network for scalable, modular control, with configuration handled through the Cortex utility.

• Open-Source & Community-Driven: Synapse PDM is fully open-source and designed to work out of the box, while still giving advanced users complete access to the firmware and hardware if they wish to customise or extend the platform. Community feedback and ongoing development continue to shape new features and future improvements.

• Powerful Integration: Built-in CAN, logging, 9-DOF IMU, and 4G/GPS SIM module make it a central hub for vehicle monitoring and advanced telemetry.

• Mature, Continuously Developing Platform: The hardware is production-ready and the firmware platform is well established, with ongoing development focused on expanding functionality, refinement, and long-term capability.

• Compact, Efficient Design: Low sleep current (~1mA) and configurable channel grouping provide reliable operation and intelligent power management without unnecessary energy consumption.

• Ideal for Technical Users: Built for engineers, builders, racers, and enthusiasts who value configurability, transparency, and the ability to tailor and expand their electrical system over time.
