You need following components:
ATMEGA328P-AU TQFP-32 *1
4*4*1.5MM Tact Switch *1
CSTCE16M0V53-RO Ceramic Crystal 16MHZ SMD-3 *1
0603 SMD Capacitor 0.1uF *2
10V 47UF 3528 Tantalum Capacitor *1
0603 SMD Capacitor 1uF 16V *1
0603 Resistor 330ohm *1
0603 Resistor 10K ohm *1
0603 SMD Red Super Bright LED *1
2.54mm 1*40 Male Pin Heard Male *1
Step 1: Solder the ATMEGA328P MCU
It will be more convenient to use the edge of the iron.You should pay attention to the direction of the pin1 of MCU.
Step 2: Solder the crystal oscillator
There are no directions of crystal oscillator. Solder the three pins to the corresponding bonding pad
Step 3: Solder the tantalum capacitor
The end which has mark on the tantalum capacitor is the negative pole. It corresponds to the round silk screen of the bonding pad.
Step 4: Solder the 0.1UF ceramic capacitor,1UF ceramic capacitor, 330R resistor, 10K resistor
Those resistors and capacitors have no anode and cathode.
Step 5: Solder the microswitch
Step 6: Solder LED
The end which has green points is the negative pole. It corresponds to the bonding pad that the silk screen points to
Step 7: Solder the pin header of the SMD
Step 8: Download the program
You can use the Arduino downloader which is developed by the ICStation. Open the Arduino IDE and Blink of routine. And choose the LilyPad arduino and COM interface, then click to download. Look, the red LED flashes. You see, it is very easy! Use ICStation LilyPad PCB circuit board to begin your design.
