A USB-C connecotr has two sets of data pins, the plug that will connect to it has just one pair. You route a single differential pair between the connector and your processor as normal (using impedance-controlled routing for the differential pair). At the connector, connect the differential pair to both sets of pins on the […]

Power delivery
USB C is able to provide up to 20V @ 5A CC pin is used for the “USB Power Delivery 2.0” single wire comms protocol. This protocol allows for much more than just power negotiations, it unlocks the advanced capabilities of the USB Type-C cable. PD messaging occurs completely independently of USB data and is […]
USB C connection to older USB devices
USB C uses a reversible connector, additional data pins and higher current capability. However, the pin usage from older USB will work just fine in many instances. Simplest connection Required:VBUS 5V inputGND 0VD+ D+D- D-Power signalling:CC1 & CC2 pin, each with a 5.1K resistor to GND. Indicates to the upstream port to provide 5V and […]
