Due to global chip shortage, I don't expect availability for the rest of the year, and perhaps further until mid next year.

IMPORTANT: This is not an end-user product and as such, it's not tested to adhere to any regulatory requirements, including interference and safety. You must therefore have basic electronics skills and know-how in order to safely and successfully use this board.

What is it?

Tiny & easy to configure module that enables use of USB‑C (USB‑PD) chargers, adapters & power banks as power sources.

Why did you make it?

In my ongoing efforts to power as many devices as possible with USB‑C (USB‑PD), I’ve found that the existing solutions were not so approachable and easy to use. Therefore, I made an attempt to improve them. Learn more at my blog.

What makes it special?

fpx introduces improvements in the following areas:

• Very small (and smaller than most other kits) at only 12mm × 21mm, while retaining configurability as well as M2 mounting holes for secure installation. Small size is important when retrofitting this module inside existing devices. For example, fpx fits in place of Thinkpad charging ports.
• Configuration is uploaded with light pulses generated by a web page. This eliminates the need for cables, wireless pairing and/or other supporting devices (such as an Arduino as was the case with fabpide2). It also means that any device that can show a webpage with javascript can configure the module. Think smartphones, tablets, PCs, laptops and even your projector. It’s of course possible to program it with an Arduino equipped with an LED as well (code for this will be available soon).
• Simplified configuration: fpx boils down the capabilities of the underlying STUSB4500 chip to two voltage and current preferences as well as a fallback setting.
• Addition of a popular µC (ATtiny 816/416) which allows hacking for additional functionality for those interested (additional µC GPIO exposed as pads on the board - requires firmware update).
