MicroRusEFI
MicroRusEFI is an open source STM32 PCB design by rusefi: a 2-layer, 80.6 × 93.7 mm board with 238 components (73 distinct parts). It is built around the STM32F427VGT6, TLE88882QKXUMA1, 500762-0481, TLE9201SG and more. Filed under sensors.
microRusEfi board for rusEfi ECU
microRusEFI is a small & cheap engine management system board designed for fully sequential 1, 2, 3 and 4 cylinder applications.
6 and 8 cylinders are possible with some limitations. 5 cylinder application not recommended. You would need at least two microRusEFI units to run a v12.
microRusEFI uses a waterproof connector and its aluminum enclosure could be sealed.
