From the project

Isolated 5V DC power supply from 230V AC mains KiCad design (educational project)

Şebeke beslemeli, izoleli 5V DC güç kaynağı modülü.

Bu proje, 230V AC şebeke gerilimini alıp izole bir transformatör, tam dalga köprü doğrultucu ve anahtarlamalı step-down regülatör kullanarak kararlı 5V DC çıkış üreten bir güç kaynağı kartıdır. Tasarım; giriş/çıkış aşırı akım koruması, gerilim darbe koruması (MOV) ve görsel güç göstergesi (LED) içerir.

- Surge Protection: Mains girişine B72314S2271K101 (275VAC MOV) entegre edildi. - Isolation Layout: AC ve DC bölgeleri PCB üzerinde fiziksel olarak ayrıştırıldı. - Branding: Silkscreen katmanına logo ve versiyon bilgisi eklendi.
