1. Attach 3 resistors and a capacitor: solder 2 of 1k ohm (brown-black-red-gold) resistors and 1 of 10k ohm (brown-black-orange-gold) resistor and 0.1uF ceramic capacitor (need to bend legs) where they are marked on the bottom
2. Flip the PCB over, put the 28-pin DIP socket (socket only while you are soldering, DO NOT insert the ATmega328p yet), the ceramic resonator (3 legs, 16MHz, with built-in capacitors), and 2 LEDs (colors doesn’t matter: green for Power and red for d13 or other way around. It’s your choice) on the top layer and solder them. **NOTE** BE CAREFUL FOR THE ORIENTATION OF THE MICROCONTROLLER CHIP AND THE POLARITIES OF THE LEDs (long leg is positive +).
3. Now it’s time to attach the male headers (Note: Depending on your project or your preference, you can put female headers (not included in the kit) or simply solder wires directly to the holes or right angle headers or whatever :-).
In order to solder the headers nicely (perpendicular to the PCB), you can use breadboard (not included in the kit) to support headers.
That’s it! Now it is ready to use.
So simple, isn’t it?
Even though pin numbers and names and PWM(~) signs are printed next to their pins, due to their small sizes, it is really hard to see with bare eyes. So I marked with black permanent marker on the side of the PCB around the FTDI pins and between the digital pins and analog pins on the other side as shown below. It really helps!
