FIDI

FIDI is a small development board running Adafruit's CircuitPython, featuring 6 terminal block connectors and a qwiic connector, designed for fast prototyping. It runs on the ATSAMD21 microcontroller, a 32-bit Arm Cortex M0+ clocked at 48Mhz, as found on many popular Arduino-compatible boards.

Questions

How big is the Fidi micro PCB?

It measures 25.4 × 22 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Fidi micro use?

32 parts, built around the ATSAMD21E18A-AF and GD25Q32CNIGR. 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 Fidi micro KiCad files?

From the omzlo/fidi-hardware repository on GitHub, at the commit this page was made from: the board is fidi-micro.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Fidi micro design in my own project?

Its repository states no licence, so its author keeps all rights: ask omzlo before reusing the design.
