Neurodots: common questions
What microcontroller does the Neurodots use?
The Neurodots is built around the RP2040, from the RP2040/RP2350 family.
How big is the Neurodots PCB?
The Neurodots measures 91.5 × 71.5 mm, has 2 copper layers and is 1.29 mm thick.
How many components are on the Neurodots?
72 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the Neurodots design files?
From the ki-manufaktur/neurodots repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Neurodots design in my own project?
The repository has no license, so all rights stay with ki-manufaktur. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Neurodots 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.
