ESP8266 D1 Board
Published
Compatible with Arduino
Introduction
1.The ESP8266 D1 Board is an open-source development board based on the ESP-8266 Wi-Fi module. It follows the Arduino UNO board layout and pin-header arrangement,integrates a Micro-USB serial chip and a 5V/1A switching power supply, and lets you write and upload programs directly with the Arduino IDE — a cost-effective choice for getting started with IoT development.
2.The board ships with its hardware and software resources fully open, allowing secondary development. You can use it directly as a Wi-Fi-enabled Arduino board, or build on it by trimming the low-level firmware and expanding peripheral interfaces. It suits IoT education, smart-home prototyping, and wireless data acquisition scenarios.

FAQ
Q1: Computer does not recognize the serial port?
A: The CH340 driver is not installed — install it; or the USB cable only supports charging — use a data-capable cable.
Q2: Cannot connect to Wi-Fi?
A: The ESP8266 supports only the 2.4 GHz band; make sure the router has the 2.4 GHz network enabled.
Q3: Board keeps resetting
A: Usually caused by insufficient power. Power the peripherals from a separate supply, or use a USB port with a higher current capacity.
