About the PCB Business Card

PCB Business Card is an open source AVR/Arduino PCB design by Bumb1eris, published on GitHub under the MIT license. It is a 2-layer board measuring 85.6 × 54 mm, with 73 components from 17 distinct parts.

Its main chip is the ATTINY1616-S, from the AVR/Arduino family. Other key parts include the MMA8451QR1 and MCP1640BX-XCHY. By type, the board carries 35 diodes, 16 resistors, 8 capacitors, 7 transistors, 3 ICs and 1 connector.

It belongs with the displays & leds, power & battery and sensors designs in this gallery.

From the project

A coin cell powered PCB business card that can play snake

A business card you can play: a tilt-controlled Snake game on a 7×5 LED matrix, powered by a coin cell.

I designed this card to hand out at TechIndustry, the largest tech expo in the Baltics. A paper card gets thrown away. A card that plays Snake gets passed around.

The original idea was a fluid simulation, but on a 7×5 matrix it just looked like random blinking, so it became Snake instead.

PCB Business Card: common questions

What microcontroller does the PCB Business Card use?

The PCB Business Card is built around the ATTINY1616-S, 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 1.6 mm thick.

How many components are on the PCB Business Card?

73 components, from 17 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 PCB Business Card design files?

From the Bumb1eris/PCB_Business_Card 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 PCB Business Card design in my own project?

Yes, under the terms of its MIT license, which Bumb1eris 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.
