• 【Arduino Compatibility】: The D1 development board is compatible with Arduino IDE, which allows you to easily program using a familiar development environment, the learning threshold and quickly realize creative ideas.
• 【Rich pin configuration】: Mini ESP8266 D1 has 11 programmable digital input/output pins and 1 ADC pin that can input 5V analog signals, providing a wide range of possibilities for connecting and interacting your project.
• 【Convenient OTA Update】D1 development board supports online OTA (Over-The-Air) update, you can easily update the firmware through the network without the need for a physical connection, which improves the convenience of development and maintenance.
• 【Efficient Power Management】Built-in 5V 1A switching power supply provides stable and reliable power to the connected external devices, ensuring stable operation of the project and reducing the risks caused by power problems.

Features:

1. Based on ESP8266EX

2. Compatible with Arduin, use Arduino IDE for programming

3.11XI/OPin

4.1XADC (input 0-3.3V)Pin

5. Support OTA Online

6. 5V 1A Integrated Switching Power Supply (Large 24V Input)

Questions requiring attention:

A diode is added to the USB power supply to prevent the external power from flowing current, and the serial port chip is directly powered via the USB terminal.

So if you don’t input 5V, you need to short circuit the E diode and let the serial port chip work.
