LumiTimeV2: common questions

What microcontroller does the LumiTimeV2 use?

The LumiTimeV2 is built around the ATmega328-A, from the AVR/Arduino family.

How big is the LumiTimeV2 PCB?

The LumiTimeV2 measures 35 × 35 mm, has 2 copper layers and is 0.8 mm thick.

How many components are on the LumiTimeV2?

53 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the LumiTimeV2 design files?

From the techn0man1ac/LumiTimeV2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the LumiTimeV2 design in my own project?

Yes, under the terms of its MIT license, which techn0man1ac chose for the repository.

Can I test firmware for the LumiTimeV2 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.
