Hardware Design Requirements I need help reviewing and completing a custom embedded controller schematic and PCB based on an ATmega328P-PU. The application details are confidential. Please focus only on the hardware implementation. Microcontroller ATmega328P-PU 16 MHz crystal oscillator ISP programming header Reset circuit 5 V, 3.3V operation Power 12 V DC input On-board 5 V regulator for the MCU 12 V rail available for loads Proper power distribution and decoupling Inputs The controller monitors six analog/digital sensing lines. Input assignments: Input A0 Input A1 Input A2 Input A3 Input A4 Input A5 These inputs are used for continuous signal monitoring. Outputs The controller drives multiple indicator groups. Required outputs: Output Group 1 Output Group 2 Output Group 3 Output Group 4 Output Group 5 Output Group 6 Each output controls multiple LEDs simultaneously through a transistor driver. The controller also drives: One 12 V buzzer User Interface One mode selection push button One reset button Deliverables Corrected KiCad schematic Completed PCB layout ERC clean DRC clean Gerber files Drill files BOM Position file
