Lightball: common questions
What microcontroller does the Lightball use?
The Lightball is built around the ESP8266EX, from the ESP8266 family.
How big is the Lightball PCB?
The Lightball measures 42.6 × 20.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Lightball?
46 components, from 27 distinct parts. The full bill of materials is listed on this page.
Where can I download the Lightball design files?
From the Jana-Marie/lightball repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Lightball design in my own project?
The repository has no license, so all rights stay with Jana-Marie. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Lightball 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.
