Electrical specs for SpeakUp ports?

[gtc]

Where may I find the electrical specifications for the GPIO ports? For instance, the max sink or source load current capability per port and total overall load current limit. I have looked in the user manual but that doesn't give this information.

Hello gtc

What you need is rather detailed, so you need to look into the datasheet of the MCU that is mounted on the speakup Click board.

The on-board MCU is STM32F415RG, which has quite a detailed specifications that are linked below:
