Pancake v8: common questions

What microcontroller does the Pancake v8 use?

The Pancake v8 is built around the nRF52840_E73-2G4M08S1C, from the Nordic nRF family.

How big is the Pancake v8 PCB?

The Pancake v8 measures 115.5 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pancake v8?

86 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pancake v8 design files?

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

Can I use the Pancake v8 design in my own project?

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

Can I test firmware for the Pancake v8 without the hardware?

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