Leddriver: common questions
What microcontroller does the Leddriver use?
The Leddriver is built around the esp8266mod, from the ESP8266 family.
How big is the Leddriver PCB?
The Leddriver measures 180 × 128 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Leddriver?
71 components, from 46 distinct parts. The full bill of materials is listed on this page.
Where can I download the Leddriver design files?
From the bitbyt3r/leddriver repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Leddriver design in my own project?
The repository has no license, so all rights stay with bitbyt3r. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Leddriver 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.
