SD ProtoBoard: common questions

What microcontroller does the SD ProtoBoard use?

The SD ProtoBoard is built around the ATTINY402-SSNR, from the AVR/Arduino family.

How big is the SD ProtoBoard PCB?

The SD ProtoBoard measures 24.8 × 36.8 mm, has 2 copper layers and is 1 mm thick.

How many components are on the SD ProtoBoard?

23 components, from 16 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 SD ProtoBoard design files?

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

Can I use the SD ProtoBoard design in my own project?

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

Can I test firmware for the SD ProtoBoard 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.
