DEV-14352

The module with connectors is dedicated to the Arduino Portenta boards. It helps in prototyping and testing connections. Arduino ASX00031

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

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

Multifunctional expander (shield) for NUCLEO and Arduino equipped with Bluetooth 2.0+EDR (HC-05) interface, MEMS 3DoF LIS35, LED-RGB, joystick and analog STLM20 temperature sensor developed and produced by KAMAMI.

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 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

Arduino IO Expansion Shield

Wixel Shield for Arduino

Shield with a 6-pin JST SH connector dedicated to Arduino Mini. It allows you to connect the GPS module with the GP-735 chip. SparkFun GPS-14030

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 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

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.

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

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
