Flashing the firmware:

  1. Press and hold the BOOT button and run: esptool.py --chip esp32 --port /dev/ttyUSB0 erase_flash
  2. Now run: esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 460800 write_flash -z 0x1000 esp32-idf4-20200902-v1.13.bin

I tested esp32-idf4-20191220-v1.12.bin and esp32-idf4-20191220-v1.13.bin from https://micropython.org/download/esp32/.

Getting infos about ESP32

While the ESP32 is connected to the serial adaptor you can run this esptool command and instantly have to press the BOOT button on the ESP32:

Questions

How big is the Hushbox fan control PCB?

It measures 57.1 × 53.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Hushbox fan control use?

34 parts, built around the DS18B20, AMS1117-5.0, IRLML2502 and MMBT3904. 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 Hushbox fan control KiCad files?

From the mhoyer/hushbox-control repository on GitHub, at the commit this page was made from: the board is pcb/hushbox-fan-control.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Hushbox fan control design in my own project?

Its repository states no licence, so its author keeps all rights: ask mhoyer before reusing the design.
