🚨 Critical Notes Before Purchase & Usage Guide

❌【Product Clarification】

This is NOT a Finished Smart Device! This is a microcontroller development board that requires programming and wiring. You must have basic electronics knowledge, programming skills, and tools like a USB cable and computer to make it work.

Voltage Forbidden Zone: The core operates at 3.3V. NEVER apply 5V to the pin labeled "3V3" or any GPIO pin, as this will instantly and permanently destroy the chip. The 5V from the Type-C port is regulated on-board.

⚠️【Common Misconceptions & Misuse】

GPIO Pins are NOT 5V Tolerant: All I/O pins operate at 3.3V logic levels. To interface with 5V devices (like an Arduino Uno), you MUST use a logic level converter. Direct connection will damage the ESP8266.

Analog Input Range Limit: The sole analog input pin (A0) can only measure up to 3.3V. Exceeding this voltage will damage the ADC. Use a voltage divider for higher voltages.

"D" Pins vs. GPIO Numbers: The labels D1, D2, etc., on the board are "user-friendly" numbers. In your code, you must use the corresponding GPIO number (e.g., D1 = GPIO5). Always consult a pinout diagram, or your peripherals won't work.

✅【Mandatory Prerequisites & Skill Level】

Required Accessories: You need to provide a Type-C USB cable for connecting to your computer for power and programming. For prototyping, a breadboard and jumper wires are also needed.

Required Skills: Basic Arduino programming knowledge (C/C++ syntax), computer literacy (installing drivers, using an IDE), and simple circuit wiring skills.

Required Software: You need to install the Arduino IDE on your computer and add ESP8266 board support via the Board Manager.

🔧【Safety Warnings & Operational Notes】

ESD Precautions: Although the board has some protection, handling with ESD care is still advised, especially in dry environments.

Driver Installation: If your computer doesn't recognize the board (no COM port), manually download and install the CH340/CH341 driver (available from official sources or seller's link).

Power Supply Stability: When using an external 3.3V power source, ensure it is clean and stable. Voltage spikes from poor-quality supplies can cause board resets or damage.
