USB Type C - only for powering my board

[FreshmanNewbie]

I want to use a USB type C cable only to power my board.

I read that by default, the USB Type C cable can give an output of 5V & 3A.



So, I am planning to have a USB type-C input connector in my board which will give the power to all my ICs from the cable.

I only want to use it for power.

My question is, in case of only using the USB TypeC for power, what should I do with the remaining pins of the USB type-c on my board?

Should I terminate certain pins or should I leave them floating? Please help.

Hi!
How many empires that can pass through the cable depends on the cross-section of the cable and, of course, on your power module. As for the rest of the contacts, it also depends on the load, if it is a "smart load" with a "handshake", then for powerful charging(Power Delivery) you should connect this (put a jumper and etc.). If you just going to use it as wire you may stay it free, but remember if you connect this wire to the USB 2.0 or 3.0 you get 500mA or 900mA only.

@FEZAR Your post isn't reflecting USB-C specifications.

To advertize device USB-C, CC pins have to be terminated with 5.1 kOhm pull-down resistors. See USB Type-C spec paragraph 4.5, part of USB 3.1.
