Unfortunately, the STUSB4500 chip is in short supply at the moment

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
