176 pin board: common questions
What microcontroller does the 176 pin board use?
The 176 pin board is built around the STM32F407IGT6, from the STM32 family.
How big is the 176 pin board?
The 176 pin board measures 61.8 × 73.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the 176 pin board?
76 components, from 31 distinct parts. The full bill of materials is listed on this page.
Where can I download the 176 pin board design files?
From the lanjay1/ECU-rusefi repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the 176 pin board design in my own project?
Yes, under the terms of its GPL-3.0 license, which lanjay1 chose for the repository.
Can I test firmware for the 176 pin board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
