The power supply is perfect, there are two switches with which you can select the output of 3.3v or 5v. in input the board can be powered with miniusb connector or with 7v-12v plug. there is a led to mark if the board is properly powered. There are various outputs that interface directly with the breadboard or can be used with wires and DuPont. I checked the outputs with a voltmeter and are perfect.

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).

Reasonable price, bought to replace that of a kit that broke in shipping, did not test

Preço razoável, comprado para substituir o de um kit que quebrou no transporte, não testei
