Makeblock MegaPi - Born to Motion Control for Maker and Geek 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 up to 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: DC 5V 3A; One Raspberry Pi switch interface (requires manual soldering) to realize 5V to 3.3V serial communication.
