l alimentatore è perfetto, ci sono due commutatori con cui poter selezionare l output di 3.3v oppure 5v. in input la scheda può essere alimentata con connettore miniusb oppure con spinotto 7v-12v. è presente un led per segnare se la scheda è alimentata correttamente. ci sono varie uscite che si interfacciano direttamente con la breadboard oppure utilizzabili con i fili e DuPont. ho controllato le uscite con un voltmetro e sono perfette. Consiglio l acquisto
This is a very smart circuit. I've been always struggling with power supplies and wires, but this addition to the breadboard makes everything more easy. Due to the onboard voltage regulators, you can choose between the 5 V and 3.3 V voltages, so you can drive different digital circuits easily. The voltages can be selected per rail (so, you can have one side at 5 V and the other at 3.3 V. There are 2 switches for it. You can power the board with an external PSU or USB (microusb).
