Aniboard: common questions

What microcontroller does the Aniboard use?

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

How big is the Aniboard PCB?

The Aniboard measures 355 × 120 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Aniboard?

384 components, from 28 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 Aniboard design files?

From the cheyao/aniboard 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 Aniboard design in my own project?

Yes, under the terms of its Zlib license, which cheyao chose for the repository.

Can I test firmware for the Aniboard 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.
