Make your projects rock solid with the Prototyping Shield. It makes it easy for you to design custom circuits and solder electronics directly on it.

## Pricing

- **Price:** $28.30 (inc GST) — $25.73 AUD, exc GST
- **Quantity discounts:** 25+ $24.44 (exc GST) · 100+ $23.15 (exc GST)

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=TSX00083:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/TSX00083:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

The ProtoShield 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 and 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.

**Key features**

- 1.0 Arduino Pinout
- 1 ICSP Connector footprint
- 2 LEDs and resistor footprint
- IOREF and GND power lines
- SPI signals pads
- 24 pin SMD footprint (50 mils pitch)

You can find your board warranty information [here](https://www.arduino.cc/en/Main/warranty).

**OSH: Schematics**

Arduino Proto Shield is open-source hardware! You can build your own board using the following files:

- [Eagle Files](https://core-electronics.com.au/attachments/localcontent/ArduinoProtoShield_V4_3505165d950.zip)
- [Schematics](https://core-electronics.com.au/attachments/localcontent/ArduinoProtoShield_V4_23688d81a90.pdf)

**Power**

The Proto Shield bring the power from the Arduino standard IOREF and GND pins to the two power bus rows placed between the Through Hole prototyping are, which can be used for powering correctly your project independently on the chosen board (3V3 or 5V).

**SPI Connection**

On the ICSP connector only 5V and GND are wired to the respective pins on the header. MOSI and MISO are present only on the connector and on the near extra pads.

For more information about the SPI communication see the [SPI library](https://www.arduino.cc/en/Reference/SPI).

**Physical Characteristics**

The maximum length and width of the Proto Shield PCB are 2.7 and 2.1 inches respectively. Three screw holes allow the shield to be attached to a surface or case. Note that the distance between digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the other pins.
