Businesscard: common questions

What microcontroller does the Businesscard use?

The Businesscard is built around the ATTINY44-S, from the AVR/Arduino family.

How big is the Businesscard PCB?

The Businesscard measures 80 × 48 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Businesscard?

32 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Businesscard design files?

From the Miceuz/LEDCard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Businesscard design in my own project?

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

Can I test firmware for the Businesscard 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.
