TableLamp: common questions

What microcontroller does the TableLamp use?

The TableLamp is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the TableLamp PCB?

The TableLamp measures 29.5 × 38 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TableLamp?

27 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the TableLamp design files?

From the fujiy/Home repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the TableLamp design in my own project?

The repository has no license, so all rights stay with fujiy. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the TableLamp 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.
