Diva card: common questions

What microcontroller does the Diva card use?

The Diva card is built around the RP2040, from the RP2040/RP2350 family.

How big is the Diva card PCB?

The Diva card measures 85.4 × 53.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Diva card?

92 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Diva card design files?

From the diva-eng/diva-card repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Diva card design in my own project?

Yes, under the terms of its MIT license, which diva-eng chose for the repository.

Can I test firmware for the Diva card 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.
