EIM: common questions
What microcontroller does the EIM use?
The EIM is built around the STM32F429ZIT6, from the STM32 family.
How big is the EIM PCB?
The EIM measures 170.6 × 121.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the EIM?
226 components, from 63 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the EIM design files?
From the bhorst519/bluecar repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the EIM design in my own project?
The repository has no license, so all rights stay with bhorst519. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the EIM 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.
