# TUSB320 Breakout Board
This PCB is a breakout board for the Texas Instruments TUSB320 chip and a USB-C connector (16+8 dummy pins).
## Features
- Headers for each pin of the TUSB320 chip and USB-C connector
- Built-in connections between the USB-C connector's CC1 and CC2 pins and the TUSB320 chip's respective CC1 and CC2 pins
- Pads for smoothing capacitors connected to voltage sources, namely VBUS and VDD. Smoothing capacitors are typically optional and you can leave them off (do not short to ground!) but filtering noise is a good practice.
- A pad for the 887K ohm resistor between the TUSB320 chip's VBUS_DET pin and the USB-C connector's VBUS pin. Note: VBUS_DET and VBUS are not connected by default.
- A jumper pad to connect VBUS_DET to VBUS with an 887K ohm resistor in between. You can either bridge the pads or use a 0 ohm resistor.
