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 :

  1. 12mA here refers to the source current and sink current is greater than 12mA.
  2. 12mA is for per pin and each pin is the same.
  3. Drive capacity current of all GPIO pins total can be 16 x 12 mA.




The sink current of GPIO is about 20mA. The maximum source current of GPIO is about 12mA.
