Mux Shield II - I/O expander for Arduino

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 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

This shield allows you to interface Wixel wireless modules to your Arduino (and other compatible products), enabling simple wireless programming, debugging, and control using standard Arduino software. Pololu 2513

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

The X-NUCLEO-53L0A1 expansion board features the VL53L0X ranging and gesture detection sensor, based on ST’s FlightSense™, Time-of-Flight technology. It is an evaluation board that provides an introduction to the ranging and gesture detection capabilities of the VL53L0X module

Gravity: Heart Rate Monitor Sensor is a sensor used to measure heart activity. Adapted for easy use with Arduino. SparkFun SEN0213

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

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

The overlay allows for easier connection of wires to the Arduino UNO R3 board. Thanks to the screw connections, it is possible to fast and securely fix the cable, and the built-in female connectors allow the application of additional Arduino shields. Screw shield

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

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

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

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

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
