不幸的是，我找不到有关 NodeMCU 的硬件规范。
所以我想了解 GPIO 电流限制、独立功耗和电路板尺寸。
或者你能分享一下关于 NodeMCU 硬件规范的链接吗？
有些页面说 GPIO Current Maximum 是 12mA，但我找不到任何自信地说。
谢谢。
最佳答案
datasheet (i.e. "Technical Reference") 没有说，但乐鑫员工回答 that question in the their forums :
- 12mA here refers to the source current and sink current is greater than 12mA.
- 12mA is for per pin and each pin is the same.
- Drive capacity current of all GPIO pins total can be 16 x 12 mA.
和
The sink current of GPIO is about 20mA. The maximum source current of GPIO is about 12mA.
