A minimal-component Arduino-compatible development board designed to learn the complete schematic and PCB layout flow for embedded system applications.
To design a compact, breadboard-friendly board using minimal components for an ATmega328P microcontroller — practicing core concepts of schematic design, PCB layout, decoupling, power regulation, and DFM.
- MCU: ATmega328P (with Arduino bootloader)
- Clock: 16 MHz crystal oscillator with load capacitors
- Voltage Regulation: LM7805 (5V), optional LM1117 (3.3V)
- Other: FTDI header, reset button, power LED
- 9V battery input via DC jack
- Onboard 5V regulation
- USB programming via FTDI header
- Standard Arduino pinout
- 2-layer PCB
- Breadboard-compatible layout
- Decoupling capacitors for MCU and regulators
- Power supply filtering
- Reset circuit and crystal oscillator layout
- DFM checked with Sierra Circuits tool
