Its main chip is the ATMEGA32U2, from the AVR/Arduino family. Other key parts include the ATECC508A and MCP73831. By type, the board carries 16 capacitors, 9 diodes, 9 resistors, 3 ICs, 3 connectors and 1 transistor.

From the project

The 2016 Crypto and Privacy Village Blinkybadge

There's no need for an extra flashing device, it has a bootloader so it can be programmed directly via usb. The only thing needed is the "dfu-programmer" software, more info: https://dfu-programmer.github.io/.

Find the Atmega device in the list. If it's already been flashed, it will show up as "dc24:1337". To get it into a mode to reflash it, follow the directions in the "Reflashing" section.

Badge2016: common questions

What microcontroller does the Badge2016 use?

The Badge2016 is built around the ATMEGA32U2, from the AVR/Arduino family.

How big is the Badge2016 PCB?

The Badge2016 measures 76.2 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Badge2016?

43 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Badge2016 design files?

From the cryptovillage/badge2016 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Badge2016 design in my own project?

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

Can I test firmware for the Badge2016 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.
