Thank you.
Works well, but the antenna they send is 315Mhz instead of 433Hhz.
It didn't come, but they solved me very quickly, so they are reliable
Exact product as the description
Everything came before the deadline. Packed perfectly! The store is good!
All right with the product and the office.
I'm in record time, thank you.
++++++++++++++++++++++++++++++++++++++
It came in time, I will Master
LOOKS VERY NICE AND CLEAN, VERY SMALL, VERY TECHNICAL. FAST DELIVER. WAS FAST and WORTH IT. THANK YOU. Soldered the ant onto the modules, looks very nice. thank you. fast delivery.
All items there, fast shipping. Recommend.
got it
Could have been better packed.
Exactly as advertised.
didn't test yet. ordered 2 pieces and they came in a reel and good packaging
Excellent. Item arrived, looks great, but I haven't tested it yet. I think everything is going to be alright. I am grateful to the store.
Perfect, just as expected. Tested the range and very easily gets 10-20m (didn't tested further as I don't need to) while going through some walls. Just keep in kind that there is no header already soldered and that the padding is 1.27mm (0.5 in). Also for the antenna, connect it on the outer pad.
