MegaPi Pro is an ATmega2560-based micro control board that is fully compatible with Arduino programming. It provides powerful programming functions and a maximum output power of 120 W. With four ports, one 4-way DC motor expansion interface, one RJ25 expansion board interface, and one smart servo interface, MegaPi Pro is highly expansible, which enables it to meet the requirements of education, competition, entertainment, etc. MegaPi Pro can be easily installed on the Raspberry Pi and connected through serial ports. The motor can be controlled by Raspberry Pi simply by using the corresponding program.
Features
Four motor driver interfaces for adding encoder motor driver and stepper motor driver, and thus to drive DC motors, encoder motors and stepper motors
One wireless communication interface for adding Bluetooth module or 2.4G module
Ten servo interfaces which enable the board to drive a maximum of 10 servos at the same time
Two high-power MOS driver interface which is able to drive devices with a maximum current of 10A. Maximum output of normal I/O ports is DC 5V 3A
One Raspberry Pi switch interface (requires manual soldering) to realize 5V to 3.3V serial communication
B-type USB interface for downloading programs and communications. It uses the CH340G USB to serial chip which can realize communication between the computer and MegaPi easily and stably
Supporting Arduino IDE programming, equipped with complete library files, and supporting the mBlock 5 block-based coding software
Compatible with Raspberry Pi，allowing you to implement the inter-control between Raspberry Pi and MegaPi

Introduction to interfaces and other plug-in modules
MegaPi uses colors to identify functions. The colors and functions are described as follows:
Red pin——power output/motor output
Yellow pin——I/O pin
Blue pin——wireless communication interface
Black pin——power GND
Green Interface–power output/motor output
Introduction to the ports
MegaPi provides four RJ25 ports identified by labels of five different colors. Their colors and functions are described as follows:
