Assembly
All connections between parts are made via traces on the circuit board. The circuit board shows exactly where the elements are placed on the board,
So it is a simple matter of inserting the parts, soldering them in place with a fine point soldering tip on which there is a minuscule drop of solder and finally trimming off any protruding wires or pins to a comfortable length.
Solder pins to the Arduino mini.
The Arduino Mini comes without pins attached.
Add the resistors to the circuit board
Solder resistors in place
Cut DuPont pin sockets to proper length
The Arduino Board connects to the circuit board via DuPont pin headers.
Cut them to length and solder them to the circuit board.
Connect the screw terminals
The screw terminals come as 2 pin units. They are designed to be joined by using the slots on each side. So, for example to make a 4 pin screw terminal, join two two pin terminals.
And the screw terminals to the circuit board
And the capacitor in the circuit board and solder in place
All The Solder Joints
Check Continuity
Insert the Arduino mini and to the DuPont pin sockets.
