What is it?

Engine control unit for port-injected gasoline engine

Capabilities

• Primary VR or Hall input (configurable with few resistor changes)

• Secondary Hall input

• Four analog temperate inputs

• 10 analog inputs

• Four high-Z injector outputs

• Two high-current low side outputs for IAC/VVT/other solenoids

• Dedicated main relay control output

• 2 low-current low side outputs for relays or warning lights

• Six high-side logic level outputs (x4 5v + x2 5v or 12v)

• H-bridge for DC motor electronic throttle body

• CAN connectivity on the plug

• USB connectivity on the plug

Why did you make it?

Nice package and high degree of integration

What makes it special?

Size, price, could be placed inside a waterproof case. And it's opensource hardware and software!

Based on stm32 arm and TLE8888 base chip.

Kit includes:

• mostly assembled board (stm32f4 soldered, op-amps soldered, H-bridge soldered etc - see picture)

• TLE8888 lqfp-100 chip

• x4 capacitor arrays

• x3 diodes

• x2 push buttons

• USB connector

• St-Link header

Altogether 13 components / 208 pads need to be soldered to finish assembly.
