A DIY desk clock with retro-style dot matrix display

- A retro-style dot matrix display: - 17x6 5mm LED matrix - Different LED colors for main area, status bar and number separator - No flickering, ghosting or uneven brightness - High refresh rate of 460Hz - 8-bit global brightness and 3-bit per-pixel brightness - Global brightness is automatically (and smoothly) adjusted by ambient conditions, just like on your phone! - Accurate timekeeping: - Temperature-compensated crystal clock (DS3231SN chip) - Backup power to keep the clock ticking (CR2032 battery) - Displays minute, hour, day…

SuperClockController: common questions

What microcontroller does the SuperClockController use?

The SuperClockController is built around the ATmega32A-A, from the AVR/Arduino family.

How big is the SuperClockController PCB?

The SuperClockController measures 139.7 × 48.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SuperClockController?

77 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the SuperClockController design files?

From the silicagel777/SuperClock repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SuperClockController design in my own project?

Yes, under the terms of its MIT license, which silicagel777 chose for the repository.

Can I test firmware for the SuperClockController 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.
