Arduino UNO Wifi ESP8266-01 CH340G Price in Pakistan

The Arduino UNO Wifi ESP8266-01 CH340G.  The Arduino Uno Wi-Fi is the same as a Arduino Uno Rev3 but with an integrated Wi-Fi module! The board is based on the ATmega328P with an ESP8266 Wi-Fi Module integrated (datasheet). 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.

The ESP8266 Wi-Fi Module is a self contained SoC with integrated TCP/IP protocol stack that can give access to your Wi-Fi network. (Or the device can act as an access point.)

It is a modernized version of the classic Arduino UNO R3 board. Full integration of a microcontroller ATmega328 and a Wi-Fi chip ESP8266 with 32 MB memory on one board. All modules can work together or individually. Each of the microcontrollers has led for connecting peripheral sensors and modules. A convenient solution for developing new projects that require Wi-Fi.

Through USB, you can update sketches and firmware for both ATmega328 and ESP8266. For this on board, there is a UART converter CH340G. The board has a DIP switch, which switches the modes of interaction of microcontrollers ATmegaa328 and esp8266.

The datasheet of  Arduino UNO WIFI is available here.

More info & typical usage

Arduino Uno Wi-Fi board will come pre-uploaded with the RestServer sketch that allows you to control the board via your web browser using the URL: http://192.168.240.1/arduino/<digital|analog>/<GPIO>/<ON_OFF|<INPUT_MODE>, where digital or analog let you select the IO type, GPIO the pin number,  ON_OFF is either  1 or 0 for on or off, and INPUT_MODE is either input or output. Some examples:

• /arduino/digital/13/1 – Sets GPIO 13 to high
• /arduino/digital/13 – Reads the value on GPIO 13
• /arduino/analog/2 – Reads Analog pin 2 value
• /arduino/mode/13/input – Set GPIO 13 to input

Packages Include:
