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

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

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

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

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

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

Nano I / O Shield for Arduino Nano is an expansion board for Arduino Nano that provides digital, analog pins, power inputs and a connector for the Bluetooth module. DFRobot DFR0012

Arduino IO Expansion Shield

(DFR0060)

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

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
