Badge2017: common questions
What microcontroller does the Badge2017 use?
The Badge2017 is built around the ESP32-WROOM, from the ESP32 family.
How big is the Badge2017 PCB?
The Badge2017 measures 95.2 × 154.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Badge2017?
129 components, from 51 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 Badge2017 design files?
From the cryptovillage/badge2017 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Badge2017 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 Badge2017 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.
