Pcb business card: common questions

What microcontroller does the Pcb business card use?

The Pcb business card is built around the ATTINY84-20MUR, from the AVR/Arduino family.

How big is the Pcb business card?

The Pcb business card measures 85.6 × 54 mm, has 2 copper layers and is 0.8 mm thick.

How many components are on the Pcb business card?

116 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pcb business card design files?

From the AG2048/pcb-business-card repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pcb business card design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which AG2048 chose for the repository.

Can I test firmware for the Pcb business card 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.
