anorith
a minimal rp2040 dev board with usb-c and onboard qspi flash.
it features
- RP2040 dual-core microcontroller as the main processor
- W25Q16JVSS 16 mbit qspi flash for program storage
- reset and boot buttons for flashing and resetting
- status LEDs for power and I/O indication
design
anorith is a small, self-contained RP2040 board built around a compact 4-layer stackup.
the board is centered on the rp2040, with a w25q16jvss QSPI flash chip providing onboard storage for firmware, and an ams1117-3.3 regulating the 3.3 V rail from USB. a 12 MHz crystal clocks the RP2040, and a pair of schottky diodes handle power-path switching between usb and the header supply. the usb-c connector, reset button, and boot button sit along the board edge for easy access during programming.

Questions
How big is the Anorith PCB?
It measures 65 × 30 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Anorith use?
45 parts, built around the RP2040, W25Q16JVSSIQ, AMS1117-3.3 and B5819W. 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 Anorith KiCad files?
From the dialgorithm/anorith repository on GitHub, at the commit this page was made from: the board is KiCad/anorith.kicad_pcb and its schematic KiCad/anorith.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Anorith design in my own project?
Its repository states no licence, so its author keeps all rights: ask dialgorithm before reusing the design.
