It has online user manual, which will guide you how to finish step by step, perfect for school basic electronics experiment projects. PCB size: 11.1 x 12.7CM Power supply voltage: 4.5~5.5V With a wire cutter, break the plastic of the header pins, and separate each header. Then, solder all the 72 header pins. Make sure all the pins are as vertical as possible. Start soldering the smallest components, and then solder the DIP sockets. Dont connect the chips yet. You should seat the chips when you finish soldering all the PCB components. Make sure you orient the DIP sockets correctly by following the half-circle orientation. When the PCB is on the following orientation, the letters of the resistor array should be facing at the back. Start by soldering the smaller components, and then the bigger ones. Pay attention to the components that have polarity. You can use the following figure as a reference on where to place each component. After soldering all the components, you can place the chips in the sockets. Place 8 LEDs in the PCB with the anode and cathode place as shown. The cathode should be placed in the headers maker with C1, C2, C3, etc. Apply 5 V to your circuit, and press the switch. The LEDs should light up and display an animation. Important note: dont start soldering any LED grids until you make sure your circuit is working properly. Build a Cardboard Grid, bend the LEDs, with the longest lead, the anode (+), to the right, and the shortest lead, the cathode (-) to the left. Using a needle nose pliers, bend the longest lead backwards with a 90 angle. Insert the LEDs into the cardboard, the LED cathode (the shortest lead) is pointing up. Solder the anodes together. Warning: Each solder joint shouldnt take more than 1 or 2 seconds, otherwise you might fry the LED. Once you have the cardboard filled with 8 rows of LEDs, you need to solder the LEDs cathodes together. Place the screwdriver between the LED rows, then, bend the LED cathodes to the right and solder the cathodes together. Warning: pay attention because the anode and the cathode rows shouldnt touch each other. Repeat steps 5 and 6 eight times until you have 8 LED grids. The next step is inserting the grids in the PCB header pins. You should connect the anodes (+) of the LEDs to the header pins. Then, connect the cathode of the first row to the C1 header pin. Connect the cathode of the second row to the C2 header pin, and so on, until you have all the rows connected to the header pins. Once youve soldered all the cathodes, test your LED grid. For that, apply power to your cube and press the switch. After the first grid is properly placed in the PCB, insert the second LED grid into the PCB. Then, solder the free cathodes leads with the cathodes leads of the previous grid. Repeat this process until you have all your LED grids in place.
