Freematics Forum

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

Dear Stanley,
I didn't see anything in the Freematics.h( library/FreematicsPlus ) that identify the VCC Pin on the Molex.
Maybe this post is too old and the code changed.

I have a One+ model b.
I need to power on/off a fan I have to install because in my area the weather is very hot and the device was stopping/sleeping too much.
It will be very interesting to control the fan with PWD too, for the moment if I can stop/start it will be enough for me.

I tried this and not work.

-- CONFIG.H
#define EXTERNAL_POWER 15

-- TELELOGGER.INO
--- inside setup()
pinMode(EXTERNAL_POWER, OUTPUT);
--- inside the loop()
digitalWrite(EXTERNAL_POWER, LOW);

Thank you !!
