QIACHIP 433Mhz Wireless Receiver Transmitter Remote Control Learning Code 1527 Decoder Module 4 CH output Learning Button


I ordered a package with
Receiver module (RX480E-4) * 10pcs
Transmitting module(TX118SA-4) * 10pcs
My order did not include the antenna's. This was also mentioned in the description, in the description where instructions how to make your own small antenna.
However i decided to also order some antenna's (5 transmit and 5 receive).

This is the product description of both modules

The first i build was a small transmitter module (using the transmitter module, a small 4 button pcb ans a battery holder.
Next i wired a receiver module up on a small veroboard with some leds resistors, a battery holder, an on off switch for the small battery. For the connection to the module i used dupont connectors so i can easy change the module. I also included the status led and a programming push button. These two items are also available on the pcb module itself so they are not really needed.
 

Later i also created a second transmitter module on a verboard with some big buttons

 
I hope to find soon more time for my next post with more info about this interesting and easy to use modules.
