USBC6P

Surface mount footprints for an easy-to-solder, 6-pin SMD USB-C connector.

Please note that this connector only connects Vbus, Gnd, CC1, and CC2. It does not pass D+ or D- data lines, or any of the other USB 2 or 3 pins.

Part numbers include USCX-06FX-XXMX-01.

Why use it?

  • Much easier to solder
  • No active negotiation to get 5V (as long as you include properly placed 5.1k resistors on CC1 and CC2)

Where to find the connector

Try searching, say, AliExpress for the phrase, usb-c 6p smd

LCSC has it as "SHOU HAN TYPE-C 6P" (part no. C456012)

What's included

Currently, Eagle footprints, a design block, and datasheet.

Do you have footprints for KiCad or another tool? Pull requests are welcomed.

How to place resistors

There are a lot of different opinions about how to connect the shield to reduce EMI. I personally like to add a 1M resistor between the 'S' (shield) and GND; you might also consider an RC network, LC network, or directly attaching to ground, depending on your device's particulars. The nice thing about adding at least one resistor/capacitor footprint is that you can always just fit it with a 0R resistor to directly connect it later--or remove it to disconnect.

Then you need to decide whether your device is a Sink (accepts current) or Source (provides current) device.

Sink

Place two separate 5.1k resistors between CC1/CC2 to GND.

Source

Place two separate 5.1k resistors between CC1/CC2 to Vbus.

What if I forget the resistors or use only one?

Fancy power supplies will deem your device unworthy of juice. Dumb power supplies won't care.

What's this zany looking multi-resistor?

The included Eagle design block (.dbl) uses a single 4-pack resistor (4x0603 -> ~1206 footprint, Bourns part no. CAY16-512J4LF) because they are terribly convenient. It's got two spare resistors for you to use somewhere else.

You can also use regular resistors of any size you like!

I spotted something wrong.
