Gravity: IO Expansion & Motor Driver Shield - an expansion board for Arduino

A development kit containing the A71CH Plug & Trust module, enabling easy and fast creation of secure IoT applications. NXP OM3710 / A71CHARD

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

Expansion board for Arduino, allows easy connection of XBee modules, has separate outputs for I2C, SPI and UART buses. The built-in 3.3V voltage stabilizer and operating mode switch make it easier to program the Arduino when the XBee module is connected to the sockets. DFRobot DFR0265

Adafruit 1141 - Adafruit Assembled Data Logging shield for Arduino

Adafruit 493 - LoL Shield BLUE - A charlieplexed LED matrix kit for the Arduino - 1.5

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

Wixel Shield for Arduino

DEV-14352

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

Cytron SHIELD-ROBO-UNO is a complete Arduino shield integrating DC motor control, servo ports, Grove/QWIIC/Stemma QT connectors, and a built-in LiPo/Li-Ion battery charging circuit. It enables rapid prototyping of robots and IoT projects, eliminating the need for complex wiring and multiple separate modules.

The overlay allows for easier connection of wires to the Arduino UNO R3 board. Thanks to the screw connections, it is possible to fast and securely fix the cable, and the built-in female connectors allow the application of additional Arduino shields. Screw shield

RGB Panel Shield is an extension in the form of shield overlays designed for Arduino. With its help it is possible to control the RGB 32x32 LED display (refresh 1: 8). Communication with the display takes place via a 2x8 connector. SparkFun SPX-14721

Expansion module with a joystick and buttons, resembling a gamepad. Enables the connection of the nRF24L01 radio module, Nokia 5110 display, Bluetooth module, I2C devices and Arduino kit. modKeyPad

Cap for Xbee and Arduino. It has been designed for wireless sensor networks such as WiFi, Bluetooth 2.0 / 4.0 and Zigbee. DFRobot DFR0015

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
