EasyArduino by ElectroIoT

The ultimate beginner’s board to learn, build, and master Arduino the easy way.

A beginner-focused custom Arduino Uno-compatible board designed for learning, soldering practice, and sensor experimentation.

🎯 Features

✅ 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

🧩 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

Connect an FTDI module to the 6-pin FTDI header

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); }
