注意:

1. The module is internally regulated by 3.3V LDO, and all digital IOs are at 3.3 LVTTL level;
2. In order to facilitate subsequent software upgrades, it is recommended to lead out the module programming pins with pin headers or connectors;
3. The EN pin cannot be directly connected to the power supply. If it needs to be connected to the power supply, a current limiting resistor must be added or a 3.3V LVTTL level control switch must be used;
