Arduino UNO WiFi R3 ATmega328P + ESP8266 8Mb USB-TTL CH340G Development Board

The Arduino Uno WIFI Board with ESP8266. The board is based on the ATmega328P with an ESP8266 Wi-Fi Module integrated. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.

Features:

• Chip CH340G – is a budget solution. When you work in the frequency 12Mhz, giving a stable result of data exchange (need install drivers to computer).
• Uno R3 CH340G/ATmega328 – connects to the computer via micro USB cable (used for almost all Android smartphones).
• You can supply power to the board through a MicroUSB connector or DC power socket.
