Arduino Proto Kit R3
The Arduino Proto Kit R3 makes it easy for you to design custom circuits . You can easily solder TH or SMD ICs on the prototyping area to test them with your Arduino board . The SMD area is designed for a maximum of 24 pins SOIC integrated circuit . The TH area contains a lot of space for the needed components around your project . You can even stick a mini breadboard (not included) on the protoarea for solderless operation . The proto area includes also two power lines (IOREF and GND), two LEDs pads and SPI signals breakout pads for boards with SPI only on the ICSP header like Zero.
