/ / Assembling the freeduino
- Unpack the kit
-
Identify and separate the following components:
R8 1Kohm resistor (RLED just below the power LED) C13 4.7uF capacitor LED 3mm green LED C8, C10 100nF ceramic capacitor C4 10nF ceramic capacitor X1 USB B PCB jack SV1 3 pin male header SHUNT Black shunt F1 PTC resettable fuse (pre-soldered on v1.19.1) 
- Solder the parts to the board, in any order.
DC1 DC power jack 2.1 mm barrel type D1 1N4004 diode C5, C12 100nF ceramic capacitor C6 100uF electrolytic capacitor (marked 200uF on the board) C7 47uF electrolytic capacitor IC2 7805 5V positive voltage regulator
R1 10 Kohm resistor R11, R12 1 Kohm resistor CRS 100nF ceramic capacitor 13, RX, TX 3mm LED R7, R9, R10 1Kohm resistors (RLED)

- Now solder the headers and sockets:
ICSP 2×3 pin male header RESET reset switch POWER, Analog In 2 x 6-pin female header Digital 2 x 8-pin female header ATMEGA168 28-pin DIP socket
- Pay special attention to the alignment of the female headers.

- Install the ATMEGA MCU.
