With the last blocker finally resolved, I updated the firmware, Python library, and GUI to use the new VID:PID pair for the PD Buddy Sink. This allowed me to make two new releases: pd-buddy-python 0.2.0 and PD Buddy Sink Firmware 1.0.0. The firmware is now guaranteed to be API-stable, so I'm very happy about that. Looking to the future, I still plan to implement support for variable and battery PDOs and finish the new circuit board. I'm planning to list two of the three v0.2 PCBs for sale on Tindie soon as well, so watch this space if you want to use USB Power Delivery in your next project!
