Light: common questions
What microcontroller does the Light use?
The Light is built around the Olimex_MOD-WIFI-ESP8266-DEV, from the ESP8266 family.
How big is the Light PCB?
The Light measures 125 × 70 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Light?
13 components, from 10 distinct parts. The full bill of materials is listed on this page.
Where can I download the Light design files?
From the 23wal/light repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Light design in my own project?
The repository has no license, so all rights stay with 23wal. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Light without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
