![]() ![]() Even beginners can make it! You'll need a soldering iron, solder, diagonal cutters and a PCB holder such as a helping hand tool. It's not a difficult project, about 30-45 minutes with a soldering iron. Project kit comes as components to be soldered to the included PCB. Onboard potentiometer for adjusting voltage from 1.25V up to within 0.5V of the input voltage.Output selection switch to select from 3.3v, 5v and Adjustable (also has a breakout for the voltage you're powering the boad with).Two indicator LEDs for high and low voltages.2.1mm DC jack and terminal connector for voltage inputs.Input diode to protect circuitry from negative voltages or AC power supplies.Short circuit and overheating protection.This means you can use a wider range of output voltages including generating 3.3V from as low as 3.7V (such as 3 AA's or a lithium ion battery)! Low dropout, only 40mV - 400mV compared to 1.25V - 2.0V for LM317.MIC2941 regulator has guaranteed 1.25A output.While there are many existing designs for adjustable power supplies, this one makes improvements that make it more useful for hobby designs A good power supply is essential to electronic projects. This kit is for making your own breadboard-friendly very low dropout adjustable power supply. ![]()
