Esattamente come lo immaginavo, non riscontro difetti. Le batterie a 3 volt sono in notevole quantità dentro la confezione e funziona tutto bene , soprattutto in campo aperto. L'alta frequenza ,433 Mhz, consente di creare piccoli dispositivi e a basso consumo. OK!!

Q: There is no technical scheme. What is the current input? How do you connect?

There was no manual/work instructions. They put a red led instead of a green led. There wasn't a 10kohm resistor. There wasn't a black screw. Integrated circuit was a TDA7388, very different from the mentionedTDA7850: less watts, can't pilot 2 ohm loudspeakers, band is 200Khz and not 300Khz like the TDA7850 reach. TDA7388 arrived with many curved and bent pins ,without protection,it's been impossible to soldering without damaging it. It's been necessary to order a new integrated circuit in UK (10,70 €) to replace the cheap and weak TDA7388 of this kit. I'm waiting for loudspeakers set, i haven't yet test this module,I hope schematic is good, but I suppose one resistor was wrong, because the muting effect shouldn't receive a so high tension,it could be dangerous in a long use period. I am not satisfied, because the principal component is not the optimum TDA7850.
