Emberone00: common questions

What microcontroller does the Emberone00 use?

The Emberone00 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Emberone00 PCB?

The Emberone00 measures 128 × 128 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Emberone00?

316 components, from 50 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 Emberone00 design files?

From the 256foundation/emberone00-pcb 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 Emberone00 design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which 256foundation chose for the repository.

Can I test firmware for the Emberone00 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.
