- Raspberry Pi GPIO Plus reference pinout board only 0.8mm thick
- Pi Traffic Light for Raspberry Pi
- Both are compatible with Raspberry Pi Models A+, B+, Zero, 2, 3, 3B+ and 4
- Reference pinout is idiot proof, really! You can’t put it on backwards
- Traffic Light mounts vertically to the Raspberry Pi GPIO header and only uses four pins
