Board overview:
- about 10 analog inputs
- One VR/Hall input channel for crank sensor
- One Hall input channel for crank sensor
- 4 injector output channels
- 4 logic level coil control channels (external igniters could be needed for some coils)
- USB
- CAN
# Capabilities
* Primary VR or Hall input (configurable with few resistor changes)
* Secondary Hall input
* x4 analog thermistor (temperature) inputs
* x10 analog voltage inputs (0-5v)
* x4 high-Z injector outputs
* x2 high-current low side outputs for IAC/VVT/other solenoids
* Dedicated main relay control output
* x4 low-current low side outputs for relays or warning lights
* x4 5v logic-level ignition outputs
* x2 5v/12v configurable logic level outputs (requires resistor changes)
* Electronic throttle body (drive by wire)
* CAN connectivity on the plug
* USB connectivity on the plug
