NeoPixI2C: common questions

What microcontroller does the NeoPixI2C use?

The NeoPixI2C is built around the ATTINY85-20PU, from the AVR/Arduino family.

How big is the NeoPixI2C PCB?

The NeoPixI2C measures 36.8 × 17.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NeoPixI2C?

6 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the NeoPixI2C design files?

From the chirimen-oh/accessories repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the NeoPixI2C design in my own project?

The repository has no license, so all rights stay with chirimen-oh. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the NeoPixI2C without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
