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

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

Adapter enabling easy and quick connection of Modulowo DuoNect to Arduino / Genuino expansion modules. MOD-75

Arduino Multifunctional Shield; LED, 7seg, buzzer, switch

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

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

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

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)

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

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

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

A module with a microSD card slot for Arduino. Equipped with two Grove connectors with I2C and UART for connecting additional sensors. Seeed Studio 103030005

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

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
