It can charge a lithium battery with a USB rechargeable battery, and the USB port can not be used as a power supply port.) or a 5V adapter be used for power supply. It can not use voltage and current unstable power supply, such as dry battery, portable charger, multi-function transformer and so on.
6>. When the Bluetooth board is installed, the antenna should not be close to the metal parts so as not to affect the transmission distance.
