Hi, Could you please suggest a superheterodyne 433mhz which shown like in your schematic? I can found only like this with 4 pins, whereas your diagram shows 8 pins. https://www.aliexpress.com/item/QIACHIP-3pcs-superheterodyne-433mhz-rf-Wireless-receiver-Module-small-size-low-power-For-433-Mhz-remote/32848494267.html

Thank you. And the antenna length is mandatory like you have mentioned? 17.4cm

dgomes commented 5 years ago

antenna length is mandatory!

vaidyasr commented 5 years ago

all I was able to find is 15cm like the one here https://www.aliexpress.com/item/NEW-Black-GSM-GPRS-Small-Suction-Cup-Antenna-433Mhz-3dbi-Magnetic-Base-1-5M-RG174-Cable/32786258061.html

Yes got it, 8dbi antenna is 17cm length.

dgomes commented 5 years ago

My diagram miss-lead you :)

When I say 17,4cm of wire it is JUST wire (no antenna at the end, the wire will be the antenna), it's cheap and easy.

If you buy a 433Mhz antenna, then you are MORE then fine :) and you don't care about the length of the cable.

Thank you, closing this issue.
