What is it?

Dianomē R2 provides power distribution, protection and 5V/3A power supply with USB Type-C, in a compact layout. In addition, with the onboard 5V/3A supply and USB Type-C output, you can power your Raspberry Pi 4 directly!

Why did you make it?

I've let the magic smoke out too many times and I wanted an all-in-one, plug-n-forget solution for my robotics projects.

What makes it special?

Thanks to inrush current limiting, it can safely drive large capacitance loads (in the range of several millifarads). It also features short protection and high-side MOSFET switching for increased safety.

Thanks to a powerful and efficient 5V/3A buck converter and USB Type-C output, you can power your Raspberry Pi 4 directly!

Provided onboard are a header for an On/Off switch for the load, a pin header for secondary 5V output, and three LED indicators, one for normal operation, one for the 5V power supply and one indicating fault.
