Hackquad: common questions

What microcontroller does the Hackquad use?

The Hackquad is built around the ESP32-PICO-D4, from the RP2040/RP2350 family.

How big is the Hackquad PCB?

The Hackquad measures 26 × 48 mm, has 4 copper layers and is 0.8 mm thick.

How many components are on the Hackquad?

91 components, from 44 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hackquad design files?

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

Can I use the Hackquad design in my own project?

Yes, under the terms of its GPL-3.0 license, which divisionind chose for the repository.

Can I test firmware for the Hackquad 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.
