Zpn devboard: common questions
What microcontroller does the Zpn devboard use?
The Zpn devboard is built around the RP2040, from the RP2040/RP2350 family.
How big is the Zpn devboard PCB?
The Zpn devboard measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Zpn devboard?
160 components, from 75 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 Zpn devboard design files?
From the CRImier/MyKiCad 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 Zpn devboard design in my own project?
Yes, under the terms of its GPL-3.0 license, which CRImier chose for the repository.
Can I test firmware for the Zpn devboard 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.
