Below are two designs for Arduino prototyping shields. They’re designed as generic boards on which you can develop any small circuit to connect to the Arduino board. One has a breadboard mounted on it, and the other has a simple PCB grid of holes.
Both of these are based on David Cuartielles’ shield design.
Breadboard shield
This shield has the reset button, the ICSP header, the I/O and power pin headers, and a small breadboard for prototyping. It also has two bus rows, one for 5V and one for ground.
| Part | Desc | Package | Part No |
|---|---|---|---|
| ICSP | 2×3 header | 2X03 | Samtec SSA-103-W-T (Qty. 2) |
| unlabeled | 1×17 female header (the two rows beside the breadboard) | 1×17 | Digikey 929974-01-32-ND (Qty 2) |
| J1 | 1×8 header | 1X08 | Samtec SSA-108-W-T |
| J2 | 1×6 header | 1X06 | Samtec SSA-106-W-T |
| J3 | 1×8 header | 1X08 | Samtec SSA-108-W-T |
| POWER | 1×4 header | 1X04 | Samtec SSA-104-W-T |
| R1 | 10K Resistor | 0207/10 | Digikey 10KQBK-ND |
| R7 | 1K Resistor | 0207/10 | Digikey 1.0KQBK-ND |
| S1 | momentary switch | B3F-10XX | Digikey SW400-ND |
| Breadboard | Solderless breadboard | Digikey 923273-ND |
A note on the Samtec headers: you can also buy long strips of these headers, because the strips can be broken into smaller pieces. You need 49 pins total, so two of part number SSA-125-W-T would do it. (the “125” indicates that they’re a single row, 25 pins).

Perfboard shield
Same as the breadboard shield, but with a grid of vias for perfboard prototyping. It also has a 5V bus and a ground bus. IT also has two LEDs which can be connected to any pin via jumper holes next to the LED.
