DFRobot- Power Shield (Arduino Compatible)

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

A module with a microSD card slot for Arduino. Equipped with two Grove connectors with I2C and UART for connecting additional sensors. Seeed Studio 103030005

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

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

Multifunctional expander (shield) for NUCLEO and Arduino equipped with Bluetooth 2.0+EDR (HC-05) interface, MEMS 3DoF LIS35, LED-RGB, joystick and analog STLM20 temperature sensor developed and produced by KAMAMI.

The shield allows for easier connection of cables to the Arduino UNO R3 board. Thanks to the screw connectors, it is possible to fast and secure the cable, goldpin connectors allow you to easily connect the servo, and the built-in female connectors allow you to put additional Arduino shields
