Clock display: common questions
What microcontroller does the Clock display use?
The Clock display is built around the ATTINY26-S, from the AVR/Arduino family.
How big is the Clock display PCB?
The Clock display measures 108.5 × 54.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Clock display?
36 components, from 21 distinct parts. The full bill of materials is listed on this page.
Where can I download the Clock display design files?
From the slomkowski/octoglow repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Clock display design in my own project?
Yes, under the terms of its MIT license, which slomkowski chose for the repository.
Can I test firmware for the Clock display 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.
