can also share power supply with other equipments. If available, a

voltage-stabilizing chip with 3.6V voltage is more recommended as the power

supplier than Switch power. But if only switch power supply available, the jam

caused by switch pulse should be avoided. In addition, a reliable grounding must be

used if there are other devices in the system. In case of failing to connect with the

ground, it can form its own grounding but must be absolutely separated from the

municipal electric supply.
