Sovereign Bunny Stack: common questions

What microcontroller does the Sovereign Bunny Stack use?

The Sovereign Bunny Stack is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the Sovereign Bunny Stack PCB?

The Sovereign Bunny Stack measures 87 × 88.9 mm, has 4 copper layers and is 1.6002 mm thick.

How many components are on the Sovereign Bunny Stack?

169 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sovereign Bunny Stack design files?

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

Can I use the Sovereign Bunny Stack design in my own project?

The repository has no license, so all rights stay with Citrullin. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Sovereign Bunny Stack without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
