Review on 📻 HiLetgo Digital FM Transmitter Module: Stereo Frequency Modulation with LCD Display by Brian Malith

So we have a relay/speaker based Christmas light show kit that turns on and off strings for either internal music or external AUX. I didn't want to disturb the neighbors or force people to roll down their windows in the Iowa winter. So I bought a speaker to line level converter so I can take the speaker output and send it to this guy for radio broadcasts! Works great, but more than quiet. Get ready to turn up the receiver volume. The sound quality was. OK, but the source wasn't exactly good. Have *some* soldering skills and maybe a 3D printer if you buy this. You need to add an antenna (I soldered a 1mm pitch pin, connected a cable to the telescopic antenna and tried to tweak the antenna a bit) and I 3D printed the case from Thingiverse. re won't beat it! Gains about 1/2 the range of the block.
