Facade60 Daughterboard: common questions

What microcontroller does the Facade60 Daughterboard use?

The Facade60 Daughterboard is built around the RP2040, from the RP2040/RP2350 family.

How big is the Facade60 Daughterboard PCB?

The Facade60 Daughterboard measures 29.3 × 43.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Facade60 Daughterboard?

34 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Facade60 Daughterboard design files?

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

Can I use the Facade60 Daughterboard design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which siderakb chose for the repository.

Can I test firmware for the Facade60 Daughterboard 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.
