Adafruit 1141 - Adafruit Assembled Data Logging shield for Arduino

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

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 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

(DFR0060)

GPS expansion module with 72-channel GNSS receiver SAM-M8Q dedicated to Arduino. The chip can receive data from all major positioning systems: GPS, GLONASS and Galileo. It has derived UART and I2C interfaces. Arduino ASX00017

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

The expansion module (shield) is designed for Arduino boards. It enables easy connection of 16x32 and 32x32 matrix displays. Requires self-assembly. Adafruit 2601

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)

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

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

(DFR0144) Relay Shield for Arduino V2.1

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
