RGB Matrix Shield - matrix display extension module for Arduino

An expansion module with a PS2 controller connector designed for Arduino boards. It communicates via the UART interface. Cytron SHIELD-PS2

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

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

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

Extension module (shield) with a signal generator for Arduino Pro Mini. It can trigger a sine, square or triangle waveform up to 3MHz. SparkFun BOB-11420

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

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

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 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

Expansion module with a joystick and buttons, resembling a gamepad. Enables the connection of the nRF24L01 radio module, Nokia 5110 display, Bluetooth module, I2C devices and Arduino kit. modKeyPad

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

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

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 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

I/O pin expander designed for Arduino platforms. Provides 48 connections to increase the number of analog inputs, digital inputs and digital outputs. SparkFun DEV-11723
