Minidriver: common questions
What microcontroller does the Minidriver use?
The Minidriver is built around the STM32G070KBT6, from the STM32 family.
How big is the Minidriver PCB?
The Minidriver measures 66 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Minidriver?
52 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the Minidriver design files?
From the adamgreig/iggie repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Minidriver design in my own project?
The repository has no license, so all rights stay with adamgreig. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Minidriver 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.
