Pyae-s-Alarm-Clock

My alarm clock is an alarm clock with 6 keys, a TFT screen, and a buzzer.

It serves as an alarm clock that I can use every day to wake up on time for school.

Features:

  • 2.25in TFT Screen
  • Buzzer for alarm
  • 6 keys to do alarm things

CAD Model

Everything fits together using 8 M3 Bolts and heatset inserts.

It has 2 different pieces, the Case and the Plate.

Questions

How big is the Pyae s Alarm Clock PCB?

It measures 70 × 65 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Pyae s Alarm Clock use?

19 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Pyae s Alarm Clock KiCad files?

From the Pyae2014K/Pyae-s-Alarm-Clock repository on GitHub, at the commit this page was made from: the board is PCB/Pyae's Alarm Clock.kicad_pcb and its schematic PCB/Pyae's Alarm Clock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pyae s Alarm Clock design in my own project?

Its repository states no licence, so its author keeps all rights: ask Pyae2014K before reusing the design.
