This board comes fully assembled and operational with header pins and terminal on the side which can be hand soldered.

What is it?

Ever thought of (re-)using your USB-C charger (like Macbook's) to power other devices? If so, this is the board for you. You can configure the chip once with your voltage/current needs and it will automatically request that voltage/current from an upstream USB-C charger. This is completely stand-alone and requires no external microcontroller. See some examples of what you can do with it in my blog post.

Why did you make it?

I was tired of having to deal with dozen power bricks of various quality. They're wasteful, bulky and sometimes unsafe for people and devices. So I decided to leverage existing high quality chargers, like Apple's, to power these devices.

Read now about this in my blog:

What makes it special?

There are other USB-PD kits out there, but they usually require a complicated software stack to talk the right protocol with the charger. STMicroelectronics STUSB4500 however, is a completely stand-alone chip that needs to be configured once.

This breakout board features:

• STUSB4500 chip capabale of negotiating from 5-20V up to 5A (provided the charger supports the output voltage/curent) — read the datasheet for more info.
• an LDO MOSFET power path that is switched on only when the charger meets the voltage/current requirements programmed.
• a discharge path to safely discharge the VBUS line when a lower voltage is configured or when the cable is detached.
• ESD protection diodes on VBUS and USB-C pins.
• Grounded M3 mounting holes.
• Header pins and screw terminal (requires soldering)
• Manufactured and assembled in USA
