Ws2812b: common questions
What microcontroller does the Ws2812b use?
The Ws2812b is built around the ESP-12F, from the ESP8266 family.
How big is the Ws2812b PCB?
The Ws2812b measures 48.3 × 48.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Ws2812b?
28 components, from 14 distinct parts. The full bill of materials is listed on this page.
Where can I download the Ws2812b design files?
From the GodenX/ws2812b repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Ws2812b design in my own project?
The repository has no license, so all rights stay with GodenX. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Ws2812b 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.
