From the project

ATmega328P based automated cat-gate controller with DRV8833 motor driver, designed in KiCad with a focus on high-current power management and noise reduction.

Bu proje, kedilerin sesli komutlarına (veya belirli miyavlama frekanslarına) duyarlı bir şekilde çalışan, otomatik bir kedi kapısı kontrol sistemidir. Donanım tasarımı tamamen KiCad kullanılarak gerçekleştirilmiştir.

Yüksek Akım ve Kalın Yollar: Motorun çalışma anında çektiği yüksek akım (inrush current) nedeniyle, güç hatlarını (VCC ve GND) standart sinyal yollarından çok daha kalın tutarak voltaj düşümlerini ve ısınmayı engelledik. Gürültü Yönetimi: Motorların devreye girerken oluşturduğu elektriksel gürültünün (noise) hassas mikrodenetleyici sinyallerini bozmaması için Ground Plane…

Cat-Gate-Controller v1.0: common questions

What microcontroller does the Cat-Gate-Controller v1.0 use?

The Cat-Gate-Controller v1.0 is built around the ATmega328P-A, from the AVR/Arduino family.

How big is the Cat-Gate-Controller v1.0 PCB?

The Cat-Gate-Controller v1.0 measures 68 × 44.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cat-Gate-Controller v1.0?

18 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Cat-Gate-Controller v1.0 design files?

From the bgmbzk/Cat-Gate-Controller-v1.0 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Cat-Gate-Controller v1.0 design in my own project?

The repository has no license, so all rights stay with bgmbzk. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Cat-Gate-Controller v1.0 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.
