Wifi Based Arduino Uno (Esp8266) ATmega328p 8Mb Flash CH340G

The Wifi Based Arduino Uno combines an ATmega328P microcontroller and an ESP8266 Wi-Fi chip with 8 Mb (1 MB) of flash on one Uno-size board, with a CH340G USB-to-serial converter for programming. It works like a normal Arduino Uno with the same headers and shields, while the ESP8266 adds Wi-Fi for IoT dashboards, web servers and remote control projects.

Wifi Based Arduino Uno Specifications

• Main microcontroller: ATmega328P, 16 MHz, 32 KB flash, 2 KB SRAM, 1 KB EEPROM
• Wi-Fi chip: ESP8266, 2.4 GHz 802.11 b/g/n
• ESP8266 flash: 8 Mb (1 MB)
• USB-to-serial: CH340G
• I/O (ATmega328P): 14 digital pins (6 PWM) and 6 analog inputs
• Form factor: Arduino Uno R3 layout, fits Uno shields
• Mode selection: on-board DIP switch sets how USB, ATmega328P and ESP8266 are connected

Wifi Based Arduino Uno Applications

• IoT sensors that send data to the cloud or a phone app
• Wi-Fi controlled relays, lights and home automation
• Small web servers and dashboards
• Adding wireless connectivity to existing Uno projects

What's in the Box

• 1 × Wi-Fi based Arduino Uno board (ATmega328P + ESP8266)

Tip: Install the CH340 USB driver if your computer does not detect the board. Use the DIP switches to choose whether you upload to the ATmega328P or to the ESP8266, then set them so the two chips talk to each other over serial once both are programmed.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
