Duex5 GPIO pins
Does anyone know the source and sink current capability of the GPIO pins when switched as an output.
I have looked for data sheet of an ESP-07 but seems only Vmin and Vmax are defined (at least on what I downloaded)
I believe from previous posts there is a 100K pullup on the board.
I would like to know if it is a driven high output or simply a sink low.
The chip that drives those I/O pins is a SX1509B. So that's the datasheet you need to look up.
Thanks for reply.
So it appears to be best case 8mA source for logic 1 and 15mA sink for logic 0.
