1.24VDC - 26VDC Variable Power Supply Educational DIY KIT for Breadboard

This kit contains all the components required to solder your very own breadboard-friendly variable power supply. The main objective of this board is to regulate the voltage that's powering your board. It uses the MIC2941 as a main chip which can supply an output voltage that varies from 1.24VDC to 26 VDC at 1.25Amps rating. This board can take an input voltage from -20V reversible to 60VDC via a standard 2.1mm jack or terminal block and also comes with reverse polarity protective diode. Moreover, it comes with a 3-position switch which can set the output voltage at either 3.3V, 5V or in adjustable mode! In the adjustable mode, onboard potentiometer for adjusting voltage from 1.25V up to within 0.5V of the input voltage. (20V max). This board also has two LEDs indicating power status and a heatsink for the IC.

The black pc board has gold plated holes for easier soldering and better quality.

Note: Requires soldering. 

Differences between the AK-252 and the AK-250: 

The AK-252 board has special circuit, the MIC2941, which can provide variable output voltage from 1.24V to 26 VDC with sharp 1.25Amps output current. It has switch and potentiometer to adjust the output voltage. Also has short circuit protection which is not available in AK-250 . On the other hand, the AK-250 uses 3 different LMs ICs for three different voltage range 3V,5V and 9V each fixed with 1 amps output current. Also, it comes with rails for choosing output voltages. The New AK-252 solves the heating and power loss problems compare to AK-250!
