Needs careful wiring

Works but be careful with VCC polarity. Markings are small. Otherwise functional for basic tests.

Reliable IR Receiver

Bought five for a classroom kit. All working perfectly. Easy to solder headers on if not pre-installed.

Good sensor, limited range

Does what it says. Range is a bit less than expected in bright light, but works great indoors for my robot.
