Works like a charm, very satisfied with it
Great set of receiver-transmitter. Despite the size, it strikes far, not less than 20-25 meters with 3.5V power.
They arrived well packed, I'm still testing them, but none of them have been defective, all in order.
The arduino fits perfectly, at 4V the power is good.
Excellent modules to connect wireless small distances. I bought them to connect the box to the apartment as a burglar alarm. Thanks Banggood
Arrived in perfect condition. Thanks.
ok
fast shipping!
I'll be fine.
