The UNI-REG Board features a Step-Down Voltage Regulator LM2576 that enables voltage to change from 7-23V AC (or 9-32V DC) to 5V, 4V, 3.3V, 2.7V or 1.8V. The board components are clearly marked, which makes the connection easier.
VOLT is a smart USB Li-Polymer battery charger. It features power management circuitry which can charge the battery over USB connector. Using provided screw terminals VOLT can also be used to power your target device from battery or USB.
The mikroDrive Board features a high-current Darlington arrays ULN2803AN and a jumper for power supply selection. The board provides an interface between a low-level logic circuitry of your prototype board and multiple peripheral power loads.
USB REG Board is a simple and compact solution for powering your prototype device directly from USB. Board provides 5V directly from USB connector, but also features MC33269DT power regulator circut for creating 3.3V reference.
