Have soldered components on the board. No instructions though, waiting for battery holder to test. Where to put positive and negative from power source as there are 4 and 2 pins separated. 4 pins have (in) and 2 pins have 5v + and negative.

the printed circuit board and the components are of excellent quality but the quantity of the components is random and the values do not correspond to what is reported on the screen printing in one kit missing a transistor while in another there are 3 leds, probably the missing transistor and what you see in the kit presentation photo

il circuito stampato e i componenti sono di ottima qualità ma la quantità dei componenti è casuale e i valori non corrispondono a quanto riportato sulla serigrafia in un kit manca un transistor mentre in un altro ci sono 3 led, probabilmente il transistor mancante e quello che si vede nella foto di presentazione del kit
