Questions
How big is the Recab PCB?
It measures 40 × 33 mm and has 2 copper layers, 1 mm thick.
What parts does the Recab use?
157 parts, built around the ESP32-S3-WROOM-1-N8, ES8311, MT29F2G01ABAGDWB-IT:G and NS4150B. 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 Recab KiCad files?
From the hung1508/Recab_mini_HW repository on GitHub, at the commit this page was made from: the board is Recab.kicad_pcb and its schematic Recab.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Recab design in my own project?
Its repository states no licence, so its author keeps all rights: ask hung1508 before reusing the design.
