FM Transmitter Module Board 0.7-9V 88-108MHz Transmit Module FM Microphone Wireless Pickup FM Transmitting MIC Board V4.0

Good and fast shipping to South Africa Item is as described haven't tested it yet I'm am satisfied with Joom and I will buy again regardless of all the bad reviews I've read about Joom they did deliver as promised!😁

Error in schematic. You must remove the 2k2 resistor and solder it between pins 2 and 3 of the IC. If you dont move it there, you won't be able to regulate output voltage with the potentiometer.

So und das Teil funktioniert überhaupt NICHT !!! Ich glaube, ich werde meine künftigen einkäufe WOANDERS durchführen ... Sorry, aber soviele Ausfälle hatte ich sonst nirgends!!!

Need töötavad hästi... Potentsiomeeter võiks kasutada suuremat väärtust kui... Ja suurus on palju väiksem, kui ma eeldasin, kuid ma olen sellega rahul

Excellent. Good quality and work as it should. On last screen comparison rtlv3 ang rsp1a. Inferences between devices is minimal.

Transistors heat up. Had transistors been positioned on same plain one could heat sink them, (with suitable insulation)

regolazioni critiche , ne555 come comparatore e driver x il relè........ comunque funziona x quello che è venduto.

Tahaksin, et tooksite selle ühendamiseks diagrammi, kuna ma ei ole ekspert, öelge mulle, kuidas seda ühendada
