Zinnia2 0 5: common questions

What microcontroller does the Zinnia2 0 5 use?

The Zinnia2 0 5 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Zinnia2 0 5 PCB?

The Zinnia2 0 5 measures 125.4 × 90.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Zinnia2 0 5?

70 components, from 28 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 Zinnia2 0 5 design files?

From the plants-tech/Zinnia 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 Zinnia2 0 5 design in my own project?

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

Can I test firmware for the Zinnia2 0 5 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.
