Intruduction
This is a simple PCB to allow a raspberry pi zero to connect to smart meters to gather statistics of power comsumption and similar. It uses the HAN-interface that many new meters have and converts it to UART signals to the raspberry pi zero.
It adds as a shield for the raspbery pi zero and provides power to the pi from the 5V-line in the HAN-interface. The HAN-interface is specified for 250mA max, so even though is could be plugged in to a normal a normal raspberry pi, it is not a good idea...
This board uses a RJ12-connector. Swedish smart meters use this connector and many other countries at least in the EU, but there are variations.

Questions
How big is the Raspberry zero han interface PCB?
It measures 65 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Raspberry zero han interface use?
27 parts, built around the BC846. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Raspberry zero han interface KiCad files?
From the grisenengineering/raspberry-zero-han-interface repository on GitHub, at the commit this page was made from: the board is raspberry-zero-han-interface.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Raspberry zero han interface design in my own project?
Its repository states no licence, so its author keeps all rights: ask grisenengineering before reusing the design.
