DFRobot - Relay Shield for Arduino V2.1

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

Arduino IO Expansion Shield

This module with three buttons and three LEDs provides easy control and visualization for electronics projects. Thanks to I2C/Qwiic communication and an STM32C011 microcontroller, the module integrates quickly with the Arduino UNO R4 WiFi and Nano, while the programmable I2C address allows for combining multiple modules in a single system. Its compact and robust design makes Buttons ideal for education, prototyping, IoT systems, and complex interactive projects. Arduino ABX00110

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

This LC8822-2020 module with eight addressable RGB LEDs allows you to create lighting effects, animations, and visual signals in electronics projects. Thanks to I2C/Qwiic communication and an STM32C011 microcontroller, integration with the Arduino UNO R4 WiFi or Nano is quick and easy, and the I2C address can be easily changed programmatically. The module is fully compatible with the Arduino Cloud and the Modulino library, allowing you to launch your first effects in minutes. Arduino ABX00109

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

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

Module with LCD display dedicated to Arduino boards. Equipped with a joystick and Gravity connectors. DFRobot DFR0287

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 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

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
