Arduino Shield - MEGA Proto KIT Rev3

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

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)

Shield dedicated to Arduino boards, which allows you to program AVR systems. Equipped with ISP connectors (6-pin and 10-pin) and a ZIF-28 base. AVR ISP Shield

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

(DFR0144) Relay Shield for Arduino V2.1

Voltage divider module for measuring quantities in the 0V to 25V range.

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

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

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

RGB Panel Shield is an extension in the form of shield overlays designed for Arduino. With its help it is possible to control the RGB 32x32 LED display (refresh 1: 8). Communication with the display takes place via a 2x8 connector. SparkFun SPX-14721

Cytron SHIELD-ROBO-UNO is a complete Arduino shield integrating DC motor control, servo ports, Grove/QWIIC/Stemma QT connectors, and a built-in LiPo/Li-Ion battery charging circuit. It enables rapid prototyping of robots and IoT projects, eliminating the need for complex wiring and multiple separate modules.
