RGB Panel Shield - an extension for Arduino to control LED displays

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

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 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

Gravity: IO Expansion & Motor Driver Shield is an Arduino compatible expansion board that provides digital I / O ports, analog I2C, SPI and UART interfaces, as well as a DC motor driver. DFRobot DFR0502

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

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

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

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
