Questions
How big is the MM36-Data Expansion PCB?
It measures 88.8 × 52.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MM36-Data Expansion use?
84 parts, built around the ESP32-S3-MINI-1-N8, TJA1051T/3/1, ADS1115IDGS and AMS1117-3.3. 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 MM36-Data Expansion KiCad files?
From the KazanNinja/MM36-Data-Hub repository on GitHub, at the commit this page was made from: the board is Kicad/MM36-Data-Expansion.kicad_pcb and its schematic Kicad/MM36-Data-Expansion.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MM36-Data Expansion design in my own project?
Its repository states no licence, so its author keeps all rights: ask KazanNinja before reusing the design.
