Custom ESP32 IoT Controller PCB – KiCad

Custom two-layer ESP32 controller PCB developed from schematic capture through physical prototype. The board integrates an ESP32-WROOM-32E module, coin-cell-backed real-time clock, piezo buzzer, user push-buttons, and screw-terminal connections for external sensors, relays, and peripherals. Project scope included: • Schematic capture and component selection • PCB placement and two-layer routing in KiCad • Power and signal-interface design • Design-rule and manufacturability checks • Gerber, drill, BOM, and assembly-file preparation • Prototype fabrication and hand assembly • Board bring-up, functional testing, and troubleshooting The design demonstrates practical experience converting an embedded-system concept into a compact, manufacturing-ready PCB.
