SD Card Shield V4 - module with microSD card slot 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

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

Shield for Arduino containing the most commonly used peripherals in an easy-to-use form. It is equipped with: OLED display, RGB diode, buttons, temperature and humidity sensor and joystick. DFRobot DFR0270

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

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

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

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

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

Wixel Shield for Arduino

Adapter enabling easy and quick connection of Modulowo DuoNect to Arduino / Genuino expansion modules. MOD-75

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

Arduino Wireless Shield

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.
