Badge2018: common questions

What microcontroller does the Badge2018 use?

The Badge2018 is built around the ESP32-WROOM, from the ESP32 family.

How big is the Badge2018 PCB?

The Badge2018 measures 124.3 × 113.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Badge2018?

97 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Badge2018 design files?

From the cryptovillage/badge2018 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Badge2018 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 Badge2018 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
