Shield-B: common questions

What microcontroller does the Shield-B use?

The Shield-B is built around the Arduino_UNO_R3, from the AVR/Arduino family.

How big is the Shield-B?

The Shield-B measures 69.1 × 53.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Shield-B?

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

Where can I download the Shield-B design files?

From the rsedak/Shield-B repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Shield-B design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Shield-B 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.
