MegaPi Pro


MegaPi Pro is an ATmega2560-based micro control board. It is fully compatible with Arduino programming. It provides powerful programming functions and a maximum output power of 120 W. With four port jacks, one 4-way DC motor expansion interface, one RJ25 expansion board interface, and one smart servo interface, MegaPi Pro is highly expansible. Its strong expansion ability enables it to meet the requirements of education, competition, entertainment, etc. MegaPi Pro can be easily installed on Raspberry Pi, and connected through serial ports. With the corresponding programs, Raspberry Pi can be used to control electronic modules, such as motors and sensors.
