BREAD Slice: common questions

What microcontroller does the BREAD Slice use?

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

How big is the BREAD Slice PCB?

The BREAD Slice measures 70 × 100 mm, has 2 copper layers and is 1.67 mm thick.

How many components are on the BREAD Slice?

35 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the BREAD Slice design files?

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

Can I use the BREAD Slice 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 BREAD Slice 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.
