Questions
How big is the Phase B PCB Prototype PCB?
It measures 83.9 × 61.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Phase B PCB Prototype use?
53 parts, built around the ATMEGA32U4-AU, 74HC595, LP2985-33DBV and USBLC6-2SC6. 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 Phase B PCB Prototype KiCad files?
From the zbayler/ENCE_3221_Class2023 repository on GitHub, at the commit this page was made from: the board is old-organization/kitchen-timer-phase-b-pcb-prototype/Phase_B_PCB_Prototype.kicad_pcb and its schematic PCB-design-(and-enclosure)/kitchen-timer-phase-a-pcb-shield/Phase_A_UnoShield.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Phase B PCB Prototype design in my own project?
Its repository states no licence, so its author keeps all rights: ask zbayler before reusing the design.
