This project contains the PCB designs designed in kicad as well as BOM and position files that wer sent off to JLCPCB for manufacturing.
Each board cost around $4 to make and ship and contains two PY32F002A microcontrollers and 32 lights/buttons. It takes 16 boards to make a full 365 day calendar.

Habit calendar: common questions
How big is the Habit calendar PCB?
The Habit calendar measures 96 × 98.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Habit calendar?
198 components, from 8 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Habit calendar design files?
From the BradleyConn/habit-calendar repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Habit calendar design in my own project?
The repository has no license, so all rights stay with BradleyConn. Use it as a reference, and ask the author before reusing the design.
