This is exquisite workmanship, superior quality Uno R3 ProtoShield Expansion Board. It possess pin headers on both sides of the back that are fully compatible with Uno R3, can be plugged directly into the Uno R3 board. The front female pin headers expand all the pins and power port of the Uno R3 board. You can do some experiments with the mini breadboard we provided. At the same time, it also reserves SPI, serial port, IIC, 1602 LCD port, NOKIA5110 LCD port, servo port, etc., which can be used after welding. In addition, it also equipped with two LED lights and two button circuits for users to use directly.
Feature

- Tailored for the Uno R3 board.
- Expand all the pins of Uno R3 board by pin headers and use them with mini breadboard.
- A large number of commonly used interfaces, SPI, serial port, IIC, 1602 LCD interface, servo interface is reserved.
- On-board two LED lights and two button circuits can be used directly.
Jargon buster
Plain-language definitions for the technical terms used above.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
