About the Anorith PCB

Anorith is an open source RP2040/RP2350 PCB design by dialgorithm, published on GitHub. It is a 4-layer board measuring 65 × 30 mm, with 39 components from 15 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the AMS1117-3.3 and W25Q16JVSS. By type, the board carries 17 capacitors, 11 resistors, 5 diodes, 3 ICs, 2 connectors and 1 crystal.

From the project

- 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

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…

Anorith: common questions

What microcontroller does the Anorith use?

The Anorith is built around the RP2040, from the RP2040/RP2350 family.

How big is the Anorith PCB?

The Anorith measures 65 × 30 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Anorith?

39 components, from 15 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Anorith design files?

From the dialgorithm/anorith repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Anorith design in my own project?

The repository has no license, so all rights stay with dialgorithm. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Anorith without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
