Years ago i Ebayed this popular cheap 4ch 433MHz remote control kit. Now that i found a use for it (arduino/ Led-lightning), i have no clue what the RX voltage should be.
I found the TX use 12V battery, that’s ok, but for the RX no data can be found. Now running 5V to be safe. However, range is only a few meters, even with a 17cm wire-antenna.
Maybe you remember this kit, and/or have the same and can help with voltage and possibly the range problem? Thanks.
