Tools required Special Features of AK-252 This Breadboard power supply module is designed to get regulated voltage from any external power source, either from the DC barrel jack or terminal block. The best part of this board is, you can use the power supply at three different modes of voltages- 3.3V,5V and at variable voltages from 1.25V to... -
Page 5: Assembly
Assembly Let’s Get Start with Soldering Follow my step by step instructions below to solder the PCB board. Carefully observe the note points that are provided. Step 1: Start with IC, place as shown. Note: Keep a little up for bending. - Page 6 Step 2: Follow up by 2.1mm power jack. Solder the two types of switches to there respective places. Solder it by placing board to the Three pin switch is on-off switch support as shown and sw2 i.e. bigger switch is an output voltage adjustable switch.
- Page 7 Step 4: For this step solder the potentiometer and diode as indicated in the picture below. Make sure the direction of the diode is same as per the PCB. Note: the silver coting of the diode is the n-side i.e. point your silver side towards the arrow symbol of the diode as shown in figure.
- Page 8 Step 6: Finally, you will solder all resistors and the terminal block. • R1: 1K • R2: 1K • R3: 20K • R4: 11K • R5: 6.2K...
