Used in conjunction with the Arduino UNO ProtoShield prototype expansion board, used to build prototype circuits can be directly soldered components on the board, you can also connect the circuit through the above mini breadboard. Between breadboard and the board through the double-sided adhesive connection, when sold breadboard and the board are separate.
The UNO Proto Shield prototype expansion board with SYB-170 mini breadboard makes it easy for you to design custom circuits. You can solder parts to the prototyping area to create your project, or use it with a small solderless breadboard to quickly test circuit ideas without having to solder.
It’s got extra connections for all of the Arduino I/O pins, and it’s got space to mount through-hole and surface mount integrated circuits. It’s a convenient way to make your custom circuit and Arduino into a single module.
