OSOYOO Sport Car for Arduino OSOYOO Sport Car Kit for Arduino is an educational and fun kit based on OSOYOO R3 MCU board (Compatible with Arduino) designed for both beginners and professionals to learn electronics, programming and robotics. OSOYOO sport car kit for Arduino uses an easy-to-install Servo Steering Rack to replace the old-fashioned Differential Steering used by most robots in the market. This Servo Steering Rack works quite similar to real car steering mechanical system and therefore has better performance. OSOYOO Motor Shield The OSOYOO Motor Shield is based on the L293DD (datasheet), which is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors.
