Marzipan: common questions

What microcontroller does the Marzipan use?

The Marzipan is built around the LPC4320FBD144, from the NXP family.

How big is the Marzipan PCB?

The Marzipan measures 120 × 75 mm and is 1.6002 mm thick.

How many components are on the Marzipan?

416 components, from 151 distinct parts. The full bill of materials is listed on this page.

Where can I download the Marzipan design files?

From the greearb/hackrf-ct repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Marzipan design in my own project?

Yes, under the terms of its GPL-2.0 license, which greearb chose for the repository.

Can I test firmware for the Marzipan without the hardware?

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