Preparation before Class 4: OSOYOO Magic I/O Shield for Arduino

Note: ALL OSOYOO Products for Arduino are Third Party Board which is fully compatible with Arduino

Arduino Uno is the most popular Arduino board, however it is often frustrating when your UNO board needs to connect many sensors and actuators with jumper wires . In worst cases, wrong connection of wires can burn Arduino board, cause circuit short-cut fire and make your project become a nightmare.

The purpose of creating the OSOYOO Magic I/O Shield for Arduino is to help people, especially beginners, to make wire connection simple, convenient and safe.

With the rich Plug and Play(PnP) connectors on the base board, you can connect standardized OSOYOO sensor/actuator modules with the Arduino Uno through this shield conveniently!

This OSOYOO Magic I/O Shield fits a standard Arduino UNO compatible board. It is a connection bridge between the electronic block module and UNO board. It has a built-in motor driver similar to L293/L298, which can provide adjustable power to inductive loads such as relays, solenoids, DC and stepping motors. Furthermore, it can drive two channels of DC motors with your Arduino board, controlling the speed and direction of each one independently.

The Magic I/O board also extends SPI port, UART, I2C, PWM and analog INPUT pins for Arduino board, so DIY enthusiasts, interactive designers can quickly attach the modules to the board for Arduino and accelerate project development progress. An intelligent power regulator allows you to connect a battery and USB cable simultaneously, and an on-board voltage switch makes it easy to change the output voltage, making 3.3V or 5V sensors compatible. With the plug-and-play interfaces, this board simplifies all your needs for an autonomous robot such as line tracer, obstacle avoidance, maze solver etc., The shield can be interfaced with 2 motors, 12 digital sensors, 6 analog sensors, a line array sensor and an ultrasonic sensor (4 pin and 3 pin).
