It is used in conjunction with the Arduino UNO Proto Shield 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.Proto Shield prototype expansion board with two buttons and two LED circuits can be directly used, all pins and power have been drawn, very fit and build circuit prototyping with Arduino.Features:It has a nice standard 0.1″x0.1″ prototyping grid with big padsComes with Stacking headers and plain header, choose whichever you want when soldering togetherAn IC pattern for adding DIP ICs up to 20 pinsPower rails down the middle and sidesA reset button and an extra general use buttonTwo 3mm general use LEDs, red and green, as well as 2 matching resistorsA pass-thru ICSP stacking header so you can stack any kind of shield on top, and/or use an AVR programmerA surface-mount chip area for up to 14 SOIC size partsCompatible with tiny breadboardsEvery pin is brought out!Gold plated pads2 x 0.1uF capacitors on either side for extra power stabilityPackage Includes:1 x Uno Proto Shield Expansion Board With SYB 170
