• ✅ ATmega328P-PU DIP – Arduino Uno compatible
• 🔌 FTDI 6-pin header for USB upload
• 🧠 ISP header for bootloader and SPI programming
• 📶 5x I²C headers with VCC, GND, SDA, SCL
• 🖲️ All digital (D2–D13) and analog (A0–A5) pins exposed with GND & 5V
• ⚡ Power input via DC jack (7–30V) and onboard voltage regulators:
  • LM2985-5.0 → 5V
  • AMS1117-3.3 → 3.3V for sensors/ESP
• 🧪 Test/learning-friendly layout with silkscreen labels
• 🔘 Onboard RESET button, Power LED, and D13 LED

• All 3-pin headers: [GND | Dn | 5V]
• PWM: D3, D5, D6, D9, D10, D11
• SPI: D10 (SS), D11 (MOSI), D12 (MISO), D13 (SCK)

• Also usable as digital (D14–D19)

GND | +3.3V | +5V | SDA | SCL

DTR | TX | RX | +5V | GND | NC

MISO | VCC
SCK  | MOSI
