Synapse PDM

Synapse PDM is an open-source, automotive power distribution module with mobile data, GPS connectivity, SD card logging, an on-board IMU and battery backup.

During my Triumph Spitfire restoration and conversion to EFI, I wanted a better solution to the whole car running on three fuses. Especially given the additional circuits required for all the EFI components, fuel pumps, ignition system and injectors.

This led me to start development of Synapse PDM. Originally a basic unit with six channels that I was going to use along side the existing fuse box. It's now grown to 14 channels which will run all the circuits in the car with a few more nice-to-have features.

I don't believe there is currently an open-source PDM of this size on the market. Much of the inspiration for this project has come from the likes of Haltech, Aim and Link. All of these companies manufacture professional, cutting-edge PDM solutions, packed with features and rugged enough to meet the demands of motorsport.

I see Synapse PDM filling a gap in the market for DIY car enthusiasts that run the likes of Speeduino or RusEFI in their cars who want a fully featured PDM without the professional-level cost.
