Slice STEP: common questions

What microcontroller does the Slice STEP use?

The Slice STEP is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Slice STEP PCB?

The Slice STEP measures 70 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Slice STEP?

22 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Slice STEP design files?

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

Can I use the Slice STEP design in my own project?

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

Can I test firmware for the Slice STEP without the hardware?

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