Filter shield: common questions

What microcontroller does the Filter shield use?

The Filter shield is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Filter shield?

The Filter shield measures 101.6 × 53.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Filter shield?

27 components, from 13 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Filter shield design files?

From the OE9SAU/SAUBerry9 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Filter shield design in my own project?

The repository has no license, so all rights stay with OE9SAU. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Filter shield 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.
