Base Shield V2 is an extension for tiles with an Arduino shield connector, it has a Grove connector, which can be connected to Grove-compatible modules / sensors. Seeedstudio 103030000

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

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

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

Arduino Wireless Shield

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

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

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

Adafruit 274 - LoL Shield RED - A charlieplexed LED matrix kit for the Arduino - 1.5

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

Shield dedicated to Arduino boards, which allows you to program AVR systems. Equipped with ISP connectors (6-pin and 10-pin) and a ZIF-28 base. AVR ISP Shield

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

LED matrix display module (in blue color) with an organization of 14 columns x 9 lines, compatible with Arduino.

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

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
