RGB Panel Shield - an extension for Arduino to control LED displays

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

An expansion module with a PS2 controller connector designed for Arduino boards. It communicates via the UART interface. Cytron SHIELD-PS2

The CAN-BUS Arduino Shield v2.0 can be stacked on an Arduino UNO, Arduino Leonardo or Arduino MEGA board. The shield integrates an MCP2515 CAN-BUS chip on the shield and has a CAN-BUS transceiver function. With an on-board DB9 and CAN-BUS connector you can choose a suitable port according to your host device. There is also an integrated MicroSD socket for data storage. DFR0370

The Beetle shield is designed to attach a Beetle controller for easy connecting servos and sensors. DFR0285

Arduino Wireless Shield

DEV-14352

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

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 494 - LoL Shield WHITE - A charlieplexed LED matrix kit for Arduino - 1.5

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

Gravity: Heart Rate Monitor Sensor is a sensor used to measure heart activity. Adapted for easy use with Arduino. SparkFun SEN0213

The shield allows for easier connection of cables to the Arduino UNO R3 board. Thanks to the screw connectors, it is possible to fast and secure the cable, goldpin connectors allow you to easily connect the servo, and the built-in female connectors allow you to put additional Arduino shields

The Bluno Beetle Shield expands the Beetle\'s single analog and digital I/O pins to the 3 pin "gravity" interface, giving more power and ground connections and making it easier to attach gravity interface modules. It also includes a convenient external power supply and a 5-8v switch to power the board on and off. DFR0356

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
