Lamp-2: common questions
What microcontroller does the Lamp-2 use?
The Lamp-2 is built around the ESP32-S3-WROOM-1-N16, from the ESP32 family.
How big is the Lamp-2 PCB?
The Lamp-2 measures 147 × 139.9 mm, has 6 copper layers and is 1.5784 mm thick.
How many components are on the Lamp-2?
248 components, from 58 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 Lamp-2 design files?
From the DodoZimmermann/lamp-2 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Lamp-2 design in my own project?
Yes, under the terms of its MIT license, which DodoZimmermann chose for the repository.
Can I test firmware for the Lamp-2 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.
