Introduction

PD Board

Tony (T 🐕)

My original buck was supposed to be able to interface with devices compatible with the USB PD standard. Basically, it should be able to interface with a Raspberry Pi and be like “yup, you can take 5 amps” and then the Pi should be like “ok bet”.

Verification of Working

How am I even supposed to know if my thing is working?

I’ll need to run hexdump -C /proc/device-tree/chosen/power/usbpd_power_data_objects.

(source: https://www.raspberrypi.com/documentation/computers/configuration.html#common-bootloader-properties-chosenbootloader)

And I should see a “binary blob containing multiple 32-bit integers”

I’ll look more into this if I actually get the board manufactured but this is a good start.

BOM

I will Definitely need to get this assembled due to the complexity of the IC. Whatever, at least I won’t have to pay for the stencil.
