USB-C Receptacle (16-pin, power + D+/D-)
16-pin USB-C receptacle — VBUS/GND/CC1/CC2/D+/D-/SBU, no SuperSpeed data. The CC pull-downs are what make a device actually power on.
Generic (various OEMs)
Overview
A USB-C receptacle broken out to VBUS (×4 physical legs, one net), GND (×4 legs, one net), CC1, CC2, D+ (×2 legs, one net), D- (×2 legs, one net) and SBU1/SBU2 — the 16-pin variant that drops the 8 SuperSpeed TX/RX differential pairs of a full 24-pin connector. That's enough for a device that only wants power (plus legacy USB2/BC1.2 charging-port detection on D+/D-), which is why it's the connector of choice for charge-only boards and 'give me 5V from any USB-C cable' designs. The part that trips people up isn't the connector itself, it's what has to sit behind CC1 and CC2: USB-C is a smart connector, not a dumb barrel jack — a compliant charger or host will not turn on VBUS at all until it sees a valid sink presentation on the CC lines, and that presentation is just two 5.1kΩ pull-down resistors, one from CC1 to GND and a SEPARATE one from CC2 to GND. Skip them, or wire one shared resistor across both CC pins instead of two independent ones, and the classic symptom is 'the board does absolutely nothing when I plug in a USB-C cable' — no smoke, no damage, just zero volts on VBUS, because nothing ever told the charger it was allowed to supply power.
Wiring tip: CC1 and CC2 EACH need their own 5.1kΩ pull-down to GND — skip that and VBUS never turns on

| A4/A9/B4/B9 | Power | Power | 5 V | 4 physical legs, one net. 5V by default; higher voltages only appear if a PD negotiation actually happens, which needs a PD-capable chip beyond just the CC pull-downs below. | |
| A1/A12/B1/B12 | Ground | Passive | — | 4 physical legs, one net. | |
| A5 | Analog | In | — | Configuration Channel 1. Needs its own 5.1kΩ pull-down to GND to present as a power sink — see externalPull. | |
| B5 | Analog | In | — | Configuration Channel 2 — electrically independent from CC1. Only one of CC1/CC2 is actually active per plug orientation (that's how the connector senses which way the cable is inserted), which is exactly why it needs its OWN separate resistor rather than sharing CC1's. | |
| A6/B6 | USB | — | — | 2 physical legs (one per orientation), tied to one net. In a power-only design these are typically left NC or shorted together per a BC1.2 dedicated-charging-port scheme, not wired into an MCU's USB peripheral. | |
| A7/B7 | USB | — | — | 2 physical legs, one net. See D+ note. | |
| A8 | Other | No connect | — | Sideband Use — floating/unused unless an Alternate Mode negotiator is present, which a power-only design doesn't have. | |
| B8 | Other | No connect | — | Sideband Use, other orientation. See SBU1 note. |

You also need
- Required5.1 kΩ resistor between CC1 and GND — Required USB-C sink presentation on CC1. Without it, a compliant USB-C charger never turns on VBUS — this is the single most common reason a USB-C powered board 'does nothing' when plugged in.
- Required5.1 kΩ resistor between CC2 and GND — Same requirement, independently, on CC2 — only one CC line is active depending on cable orientation, so both need their OWN resistor. A single resistor shared across CC1 and CC2 is out of spec and can confuse orientation detection.
- Without both CC pull-downs present and separate, expect exactly zero volts on VBUS from any spec-compliant USB-C charger — there's no fallback to 'just supply 5V anyway' the way an old USB-A port would.
- This bare-minimum wiring gets you the default 5V/up to ~500mA-900mA (some chargers extend this via legacy BC1.2 D+/D- signaling). Drawing more current, or negotiating a specific voltage, needs an actual USB-PD sink controller IC reading the CC lines — the two resistors alone only get you 'basic power available', not PD negotiation.

Frequently asked questions
What voltage does the USB-C Receptacle (16-pin, power + D+/D-) run at?
The USB-C Receptacle (16-pin, power + D+/D-) runs at 5V, per the spec sheet below. Always double-check against the specific board you have — some breakouts add an onboard regulator that changes the usable input range.
How many pins does the USB-C Receptacle (16-pin, power + D+/D-) have?
The USB-C Receptacle (16-pin, power + D+/D-) has 8 pins. See the full pinout table in Pins & wiring for each pin's role.
Can I simulate the USB-C Receptacle (16-pin, power + D+/D-) before ordering hardware?
Not yet — the USB-C Receptacle (16-pin, power + D+/D-) does not have a live simulation model in Banana Board today, so validate the wiring here and test on real hardware.
Where is the USB-C Receptacle (16-pin, power + D+/D-) datasheet?
Linked in the Documents section on this page, and cited on every spec that came from it.
