Solid Hat Industrial Electrical

Small, sturdy relay board, well folded. Provides a pass-through expansion port. Be careful with too long relay solder connections on the underside of the board as they can short out if they touch the Pi - it's best to use spacers or insulators.

Pros
  • Excellent design
Cons
  • No instructions
