Placa de desarrollo R3 WeMos WiFi R3 ATMEGA328P/PB Chip CH340G para placa de desarrollo UNO R3 Arduino WeMos ESP8266

ATMEGA328P Chip CH340G For Arduino UNO R3 Development Board

This version is optimized on the original version, mainly designed for foreign customers with high product quality and functional requirements. It is guaranteed to be completely consistent with the original version and convenient for everyone to use.

Advantages:
1 completely solved the incompatibility of the traditional UNO board in win7 and win8 system.
2. The pin header is added to facilitate the use of the DuPont line.
3. Replaced 16u2, reducing costs to half, consumers get the most benefits

Instructions:
1. Download arduino's IDE
Download address: (copy open)
2. Download the USB chip driver

Feature description
Open the circuit diagram of the original design, the development software interface is free to download, and you can also modify it yourself according to your needs. The downloading program is simple and convenient. You can simply use sensors and various electronic component connections (such as: LED lights, buzzers, buttons, photoresistors, etc.) to make a variety of interesting works.

Using the high-speed microprocessor controller (ATMEGA328), the development operation interface and environment are very simple and easy to understand, which is very suitable for beginners to learn.
