Quatro: common questions

What microcontroller does the Quatro use?

The Quatro is built around the STM32F405RGTx, from the STM32 family.

How big is the Quatro PCB?

The Quatro measures 100 × 72.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Quatro?

98 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the Quatro design files?

From the Teruru-52/Mercury-pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Quatro design in my own project?

The repository has no license, so all rights stay with Teruru-52. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Quatro without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
