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

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

Wixel Shield for Arduino

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

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

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

(DFR0144) Relay Shield for Arduino V2.1

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

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

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

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

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

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

Shield - Xbee w / o RF module

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

WiFiBee-MT7681 is an XBee module based on the MT7681 Wi-Fi module. WiFiBee supports standard IEEE802.11b / g / ni protocols. Can be used as a remote programmer for Arduino tiles. It is powered by 3.3 V. DFRobot TEL0107

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