SKB378 规格书 datasheet
It is recommended to reserve a 4Pin port for firmware downloading or software upgrading. It is
recommended to reserve electrostatic protection devices (can be NC) at the burning port.
3.复位脚内部已经上拉到 VCC，外部无需上拉，如需使用按键复位，请预留防抖动电容，并靠近按键
处放置一个 ESD 保护器件。
The reset pin has been pulled up to VCC internally, so there is no need to pull up externally. If you need
to use the button to reset, please reserve an anti-shake capacitor and place an ESD protection device
near the button.
4.其余 pin 脚做按键时，建议同复位脚一样预留保护电路，如需做低功耗建议使用外部<2.1MΩ的上
拉电阻。
If other pin pins are used as keys, it is recommended to reserve protection circuit same as the reset pin.
If low power consumption is required, please use external pull-up resisters (< 2.1MΩ).
5.IO 口驱动能力有限，单个 IO 口驱动电流最大 50mA，所有 IO 口最大电流加起来不得超过 200mA，
如需驱动大电流时，请用外部三级管或者 MOS 管驱动。
The current driving capacity of IO port is limited. The maximum driving current of a single IO port is
50mA, and the total maximum current of all IO ports shall not exceed 200mA. If large current needs to be
driven, please use external triode or MOFET.
