Screw Shield for Arduino

Extension module (shield) with a signal generator for Arduino Pro Mini. It can trigger a sine, square or triangle waveform up to 3MHz. SparkFun BOB-11420

The expansion module (shield) is designed for Arduino boards. It enables easy connection of 16x32 and 32x32 matrix displays. Requires self-assembly. Adafruit 2601

This shield allows you to interface Wixel wireless modules to your Arduino (and other compatible products), enabling simple wireless programming, debugging, and control using standard Arduino software. Pololu 2513

The Bees shield is compatible with Arduino boards such as UNO R3 and Leonardo it has a large prototyping shield giving you plenty of space to experiment and add extra components to your project. Thanks to its uniform interface, there are a huge number of devices compatible with the xBee socket: xBee, WiFi xBee, Bluetooth Bee, zigBee, etc. DFR0210

The module with 4 relays is designed to work with Arduino. It allows you to control devices with operating parameters up to 250VAC/7A or 30VDC/10A. Seeed Studio 103030009

(DFR0105) Power Shield (Arduino Compatible)

Powerful expansion shield for Arduino Mega. It is large enough to carry up to 3 Xbee slots, 1 microSD slot and shield headers for most Arduino shields on the market. DFR0165

Wixel Shield for Arduino

Voltage divider module for measuring quantities in the 0V to 25V range.

Shield with a 6-pin JST SH connector dedicated to Arduino Mini. It allows you to connect the GPS module with the GP-735 chip. SparkFun GPS-14030

GPS expansion module with 72-channel GNSS receiver SAM-M8Q dedicated to Arduino. The chip can receive data from all major positioning systems: GPS, GLONASS and Galileo. It has derived UART and I2C interfaces. Arduino ASX00017

4inch Touch LCD Shield for Arduino is an overlay with a 4-inch LCD display. The screen has a resolution of 480x320 pixels. Communication with the display is via the SPI interface. Waveshare 4inch TFT Touch Shield

Extension board for Arduino Nano and Uno, 14 GPIO lines, connectors with I2C and UART interface lines. The board also has a RESET button and a voltage stabilizer

e-Paper display controller module with a standard Arduino connector. It has a built-in MX25R6435F Flash memory with a capacity of 8 MB and a 24-pin FFC connector dedicated to e-Paper displays. Waveshare e-Paper Shield (B)

I/O pin expander designed for Arduino platforms. Provides 48 connections to increase the number of analog inputs, digital inputs and digital outputs. SparkFun DEV-11723

The overlay solves the problem of limitations in the use of multiple overlays compatible with Arduino UNO R3. The board allows you to connect different shields without their mutual influence on each other (eg without conflict on the UART bus or GPIO lines). Extension dedicated for Arduino Mega and ADK devices. DFRobot DFR0256
