To buld the ESP32 firmware:
- Install the ESP32 toolchain for your OS. You do not need to install the ESP-IDF -- that happens automatically in the next step.
- For Linux: https://esp-idf.readthedocs.io/en/v3.2/get-started/linux-setup.html
- For Windows: https://esp-idf.readthedocs.io/en/v3.2/get-started/windows-setup.html
- For OSX: https://esp-idf.readthedocs.io/en/v3.2/get-started/macos-setup.html
-
Pull in the ESP-IDF, MicroPython, and other dependencies:
git submodule update --init --recursive -
Build mpy_cross:
cd firmware/esp32/components/micropython/micropython/mpy-cross/ && make && cd ../../../.. -
Optionally configure the serial port that your badge appears on (under Serial Flasher Config):
make menuconfig -
Build it:
make -j5 -
Flash it:
make flash
The EFM8 firmware has only been built inside Simplicity Studio.

Questions
How big is the Badge2018 PCB?
It measures 124.3 × 113.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Badge2018 use?
118 parts, built around the ESP32-WROOM-32 and RT9524GQW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Badge2018 KiCad files?
From the cryptovillage/badge2018 repository on GitHub, at the commit this page was made from: the board is hardware/badge2018.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Badge2018 design in my own project?
Its repository states no licence, so its author keeps all rights: ask cryptovillage before reusing the design.
