FunHomeLight: common questions
What microcontroller does the FunHomeLight use?
The FunHomeLight is built around the ESP32-C3-WROOM-02, from the ESP32 family.
How big is the FunHomeLight PCB?
The FunHomeLight measures 44 × 44 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the FunHomeLight?
17 components, from 11 distinct parts. The full bill of materials is listed on this page.
Where can I download the FunHomeLight design files?
From the ZhiFun/FunHome repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the FunHomeLight design in my own project?
Yes, under the terms of its MIT license, which ZhiFun chose for the repository.
Can I test firmware for the FunHomeLight 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.
