Hardware repo for modular-things custom circuits. Each folder includes a shematic image, board image, and relevant design files in a Fusion 360 Archive.

/samd21 contains the OG modular-things circuits based on the ATSAMD21E18A

/xiao contains newer designs based on the seeed xiao development boards, in particular the RP2040 version

/backpacks contain modular PHY add-ons, in development

/jewel contains the stub of a usb-power-delivery based xiao-like module we are ~ planning

To design a new board, you can start with the base design for samd21s or the base design for the xiao platform.

Note that it is also possible to virtualize almost any existing arduino project as a modular-thing - these circuits are just a cohesive, demonstrative set.
