Signet hc: common questions

What microcontroller does the Signet hc use?

The Signet hc is built around the STM32F733IEKx, from the STM32 family.

How big is the Signet hc PCB?

The Signet hc measures 16 × 28.4 mm, has 6 copper layers and is 1.016 mm thick.

How many components are on the Signet hc?

53 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Signet hc design files?

From the nthdimtech/signet-hc-pcb repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Signet hc design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which nthdimtech chose for the repository.

Can I test firmware for the Signet hc 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.
