CANBoard: A simple IO expansion board that supports CAN bus, suitable for steering wheels/button boxes/control panels, etc.

Overview

CANBoard is a simple IO expansion board that supports CAN bus, designed for devices such as steering wheels/button boxes/control panels. Features 8 digital inputs (Ground switching) 5 analog inputs (5V max) 4 digital outputs (low-side switch: open-drain output, maximum load current per channel: 0.5A) Main control chip: STM32F303K8 Design tool: KiCad 7.0.0 Design goal Low cost: Provide an economical and practical solution for personal modified car projects. Easy manual welding: Use 0805 package components, and give priority to commonly used stock devices (such as LD1117S33CTR linear regulator). Open source sharing: Public design files for others to refer to, improve or collaborate on development.
