我在数据手册和参考手册里都没有发现关于io引脚输出电流的信息。

请问在哪里可以找到这些内容?

Hello,

Actually, GPIO buffer load capacity is not specified in units of current. It is only specified in terms of buffer drive strength or output impedance. You can refer to section 4.3.3.1 "Single Voltage GPIO Output Buffer Impedance" of the DataSheet.

Please keep in mind that these pins are not meant to supply current, so you have to be really careful to avoid damages.

Hope it helps!

Victor.
