Paper badges: common questions

What microcontroller does the Paper badges use?

The Paper badges is built around the ESP-12E, from the ESP8266 family.

How big is the Paper badges PCB?

The Paper badges measures 99.6 × 57.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Paper badges?

66 components, from 31 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 Paper badges design files?

From the dodgymike/bsidescpt2016badge repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Paper badges design in my own project?

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

Can I test firmware for the Paper badges without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
