Sigvision logic analyzer: common questions

What microcontroller does the Sigvision logic analyzer use?

The Sigvision logic analyzer is built around the STM32F411CEUx, from the STM32 family.

How big is the Sigvision logic analyzer PCB?

The Sigvision logic analyzer measures 116 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sigvision logic analyzer?

19 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sigvision logic analyzer design files?

From the santtos0x1/sigvision-logic-analyzer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Sigvision logic analyzer design in my own project?

Yes, under the terms of its Apache-2.0 license, which santtos0x1 chose for the repository.

Can I test firmware for the Sigvision logic analyzer 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.
