README
README.mdThunderMini Brushless Motor Driver
A modular, stackable brushless motor driver platform based on the TMC6200, TMC4671, and STM32G473.
Overview
ThunderMini is a brushless motor driver system consisting of three separate PCBs that can be stacked together or used individually, depending on the application.
Boards:
-
ThunderMini: Main power stage based on the TMC6200 3-phase gate driver.
-
Thunder4671: Control board based on the TMC4671 for hardware-based FOC control.
-
ThunderSTM32: STM32G473 microcontroller board used to control the TMC4671 or to run software-based FOC control (e.g. SimpleFOC).
This project is work in progress and is NOT ready to use.

Questions
How big is the ThunderMini PCB?
It measures 51.7 × 51.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ThunderMini use?
79 parts, built around the TMC6200-TA and BSC014N06NS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ThunderMini KiCad files?
From the YaseenTwati/ThunderMini repository on GitHub, at the commit this page was made from: the board is thunder_mini/ThunderMini.kicad_pcb and its schematic thunder_4671/Connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ThunderMini design in my own project?
Its repository states no licence, so its author keeps all rights: ask YaseenTwati before reusing the design.
