Web1.17 Is it really necessary to provide external ESD protection in case of no ESD protection for GPIO pins of a microcontroller built in? It is only necessary to protect GPIO exposed to system-level ESD (connector, button) otherwise embedded HBM is enough. 1.18 Can you explain why ESD protection is needed with a USB-C connector housed in a ... Web21 hours ago · Can a gpio-leds device have a supply? I have a board with GPIO driven LEDs. These LEDs can only be activated if the power supply is on. To do this, I have to set on a GPIO "led_enable". I think I will have to use a regulator but I don't know how to declare the LED device as a consumer of this regulator. Is something like that do-able ?
