Noraiz963/Home-Automation-by-using-esp32_WROOM32D-pcb-
An ESP32-based home automation controller designed in KiCad combines an isolated AC-DC power supply, dual relay outputs, physical switch input, and UART programming header into a single board for controlling AC loads…
Noraiz963/AC-to-DC-converter-
A basic AC to DC converter circuit designed in KiCad — full-wave bridge rectifier with capacitor filtering. First PCB design project.
Noraiz963/Boost-Converter-
A DC-DC boost converter designed in KiCad, built around the XL6009 adjustable boost converter IC steps up a lower input DC voltage to a higher, adjustable output voltage.
Noraiz963/DC-Motor-Controller
A 555-timer-based DC motor speed controller designed in KiCad — uses a variable-duty-cycle PWM signal driven through a power transistor to control motor speed with a single potentiometer.
Noraiz963/Dual-Motor-Driver-Board
A dual H-bridge motor driver board designed in KiCad, built around the DRV8833RTY IC drives two DC motors independently (forward/reverse/speed control), commonly used for small robotics platforms.
Noraiz963/Servo-tester
A simple 555-timer-based servo tester designed in KiCad — generates a variable-width pulse signal to manually test and center RC servo motors without needing a microcontroller or transmitter.
Noraiz963/Transformerless-DC-power-supply
A capacitor-dropper based transformerless power supply designed in KiCad, converting AC mains input into a regulated 5V DC output without using a bulky step-down transformer.
Noraiz963/USB-to-Serial-Converter
A minimal USB-C to UART bridge board built around the CP2102 USB-to-UART bridge IC. This board exposes TX, RX, RST, VBUS, and GND on a standard header, letting you connect any UART-based microcontroller or device to a…
