5V VCC Pin

Postby NatroN » Tue Sep 11, 2018 8:28 pm

Hi everybody -

I tried to find it in the Products page of the One+ but I had no success. How much power can I draw from the 5V VCC Pin (Molex - GPS) continously? Is it possible to switch it on/off via software or do I have to built some sort of relay / transistor and use the gpio next to it?

thanks

The Molex VCC pin is 5V and can be switched on/off by a ESP32 GPIO (check FreematicsBase.h).

perfect for my needs - thank you. Do you know how much power I can draw? Thinking about running an USB Hotspot on it
