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 voltage 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.

    Firmware update

After a new firmware version is released, you can connect Pocket Shield to mBlock 5 through CyberPi to view and update its firmware. For details about how to update the firmware, see “How to update the firmware?“

Programming

You can use mBlock 5 to program Pocket Shield. 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).

For details about programming, see “Programming Software.”
