4通道 315MHz 無線接收器 附遙控器

Wired it up to my garage door opener in about ten minutes and each button on the fob triggers its own output pin cleanly, no cross-talk between channels. The range is solid for a 315MHz unit, even through one wall.

The four individual buttons on the fob respond instantly, and I love that each one controls a separate output pin without any confusing setup. Hooked it up to some LED strips in my workshop, and it’s been rock solid so far.

Wired this up to my garage door and the four buttons map perfectly to each output pin on the receiver. The fob feels solid in the hand, and pairing took maybe two minutes with the included instructions. Exactly what I needed for a simple remote setup.
