SafestepHW: common questions

What microcontroller does the SafestepHW use?

The SafestepHW is built around the ESP32-C3-MINI-1, from the ESP32 family.

How big is the SafestepHW PCB?

The SafestepHW measures 50.1 × 50.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SafestepHW?

26 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the SafestepHW design files?

From the 8-BitLab/safestep repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the SafestepHW design in my own project?

The repository has no license, so all rights stay with 8-BitLab. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SafestepHW 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.
