🧩 Pinout Overview

🔌 Digital Pins (D2–D13)

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

📈 Analog Pins (A0–A5)

  • Also usable as digital (D14–D19)

📡 I²C (5x Headers)

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

⚙️ UART & FTDI Header (6-pin)

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

🛠 ISP Header (2×3)

MISO | VCC
SCK  | MOSI
RST  | GND

🛠 Getting Started

🔧 Uploading Code

  1. Connect an FTDI module to the 6-pin FTDI header
  2. In Arduino IDE:
    • Select Board: Arduino Uno
    • Choose correct COM port
    • Upload your sketch!

🔌 Powering the Board

  • Use DC Barrel Jack (7–30V)
  • 5V & 3.3V rails automatically regulated onboard

🔍 I²C Sensor Example

Plug sensor into any I²C header and use code like:

#include <Wire.h>

void setup() {
  Wire.begin(); // I2C init
  Serial.begin(9600);
}

void loop() {
  Wire.beginTransmission(0x76); // Example address
  Wire.write(0xF4); // Example command
  Wire.endTransmission();
  delay(1000);
}

🧠 Educational Ideas

  • Solder-it-yourself Arduino kit
  • I²C sensor lab: OLED, BME280, RTC
  • Learn SPI, I2C, UART, PWM
  • Expand with ESP8266 via UART/I²C
