I’m wondering how difficult, both technically and financially, it would be to incorporate USB - C power delivery port. Instead of relying on barrel jack for power. Would making one less thing for us travelers to carry. Many of us are powering a laptop, likely a phone also with USB-C already. It would be great to be able to power my travel router with the same User Friendly port!
Can anyone else relate??!
I dare say i’d be smitten with a convexa S with a usb-c power port.
The Micro-B USB is slightly smaller than the Mini and is the most widespread USB port design for current smartphones and tablets. At 8.3 x 2.5 mm, the Type-C port and connector are approximately the same size as that of the Micro-B USB, making it tiny enough to work for even the smallest peripheral devices.
So are you telling me that a USB-C charger will not supply 5V default on the usual usb power lines, and won’t negotiate a higher voltage if the devices allows?
If so then all the specs i have seen of USB-C are wrong, and lots of devices should be blowing up.
I’m looking at the spec by TI right here:
Page 8, “VBus defaults to 5V, 500mA power supply”
Swapping out the SMD micro usb for a USB-C on the board, connecting the same usb2 connections and adding 5.1k pulldown resistors to CC1 and CC2 is enough for it to work with USB-C power hosts and for usb2 speed data transfer.
