README
README.mdSPRO-2: Motor Control & Generator Project
🟦 Project Overview
This repository contains the hardware designs and firmware for our university semester project (SPRO-2).
📂 Repository Structure
🔌 Hardware
The hardware is designed in KiCad and is split into three main modules:
- Control Board: The "brains" of the operation, handling logic and signal processing.
- Generator Board: Responsible for power generation and distribution.
- Current Sensor Test Board: A dedicated board for validating the current sensing circuitry before full integration.
💻 Firmware
(Coming Soon) The firmware will handle the motor control algorithms, sensor data acquisition, and communication logic.
🛠 Tech Stack
- PCB Design: KiCad 10.0
- Firmware: C / Arduino
- Documentation: LaTeX

Questions
How big is the Generator board PCB?
It measures 142 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Generator board use?
31 parts. 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 Generator board KiCad files?
From the tkqa1ex/SPRO-2 repository on GitHub, at the commit this page was made from: the board is motor-PCB/generator-board/generator-board.kicad_pcb and its schematic motor-PCB/control-board/control-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Generator board design in my own project?
Its repository states no licence, so its author keeps all rights: ask tkqa1ex before reusing the design.
