mBot2 Shield

Overview

mBot2 Shield is equipped with a built-in rechargeable lithium-ion battery that can supply power for CyberPi. With the multi-function, servo, and motor ports, it can drive motors, servos, and LED strips.

Features

  • Built-in rechargeable lithium-ion battery, used to supply power for CyberPi
  • Two multi-function ports, used to connect and drive not only servo but also LED strips
  • Two servo ports, used to connect and drive servos
  • Two DC motor ports, used to connect and drive DC motors
  • Two encoder motor ports, used to connect and drive encoder motors
  • One CyberPi port, allowing you to easily connect mBot2  to CyberPi
  • Supporting Python programming, for which the cyberpi library is provided

Note:

  • Self-discharge occurs in the lithium-ion battery. If you store mBot2 Shield with the battery voltage lower than 3.6 V for a long time, the battery will be over-discharged and its internal structure may be damaged, which reduces the endurance of the battery. Therefore, to store mBot2 Shield for a long time while keeping the battery intact, you need to charge the battery once every three to six months to 3.8–3.9 V (the best coltage for storage is 3.85 V), which allows the discharge depth of 40% to 60%.
  • Store mBot2 Shield at 4℃ to 35℃ in a dry place or keep it away from moisture through packaging.
  • Keep it away from heat or direct sunlight.

Programming

You can use mBlock 5 to program mBot2. mBlock 5 provides two editors, namely the block-based graphical editor (the default editor, referred to as mBlock 5) and Python editor (referred to as mBlock-Python Editor).
