The Sparkdog PF extension PCB is a plug in controller for the Rabbit ECU. It provides an alternative to the Arduino Due controller, providing for the Teensy 3.5 instead.

Additionally, the Sparkdog PF extension PCB hosts a second MK10 microcontroller that controls a 4-channel H-Bridge driver, 4-channel Hall Effect VVT inputs, 2-channel VVT outputs and a powerful PWM mode solenoid driver.

I made the Sparkdog PF extension PCB to allow users to integrate a more powerful DIY controller and add all the hardware needed to run a modern DBW VVT engine.

The PCB is populated with all of the components that appear in the schematics, and is supplied with the headers so you can attach the Teensy 3.5 that is sold separately.

The PCB is 100% compatible with Rabbit ECU V1.2 and V1.3, so is an excellent upgrade path from Arduino Due.
