This was achieved by using SMD components and placing the Arduino upside-down on top of the PCB. The unique stacking arrangement allows the unit to be particularly thin for a unit that still uses a separate Arduino MEGA. It is a 4+4 board that incorporates the follow features. - Four injector channels -- Four ignition channels +- Four ignitor channels - Outputs for VVT, 2x PWM idle, boost, fuel pump, tachometer, and 2x fan - Four auxilary outputs -- Built in stepper control (versions C) +- Built in stepper idle control (versions C) - Two trigger inputs - Launch input -- Two additional interupt inpute designated as flex and knock* +- Two additional interupt input designated as flex and knock* - Analog inputs for CLT, IAT, TPS, and O2 - Two auxilary analog inputs +- MAP and baro sensor onboard - Two GPIO connections that breakout inside the case Latest version: C5 -*Knock is currently unsupported in the firmware +*Knock is currently unsupported in the firmware. Either input can be used for VSS. ## NO2C The No Overhang Two Channel was designed to incorperate as many features as possible into a through-hole board that does not exceed the dimensions of the Arduino MEGA microcontroller it sits on top of. It is a 2+2 channel board that incorperates the features below. - Two injector channels
