The BYH DevBoard exposes nearly every RP2040 GPIO pin through standard 2.54 mm headers, making it compatible with breadboards, jumper wires, sensors, displays, and common development modules.
Commercial RP2040 development boards are excellent, but I wanted to understand what goes into designing one from scratch.
This project gave me hands-on experience with:
- RP2040 reference design
- High-speed USB routing
- Power supply design
- PCB layout best practices
- Component sourcing
- Manufacturing preparation
- Hardware documentation
- USB ESD Protection
- Power LED
- User Programmable LED
- SWD Debug Header
- Castellated Edge Version
- Battery Support
