Hi danny8376,

The maximum source current of GPIO is about 12mA.

Thanks.

Dear Sir,

The sink current of GPIO is about 20mA.

Thanks.

Is there any info about peak source current ?

Dear Sir,

The sink current of GPIO is about 20mA.

Thanks.

@Espressif_Kelly You said that "sink current is greater than 12mA." - do you have a figure for how much current can be sunk per pin?

Many thanks,
Ben

Dear Sir,

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.

Thanks for your interests in ESP8266EX!

Is there no answer to this question?

GPIO Maximum current Imax

I see in the spec that it says:

Maximum Drive Capacity Imax 12 mA.

Is that the same whether source or sink?

Is that per pin, or for all pins total?

If per pin, what is the maximum for all GPIO pins together, as I doubt it is as much as 16 x 12 mA.

Thanks,
Peter
