The UNO+WiFi R3 ATmega328P + ESP8266 (32Mb Flash) USB-TTL CH340G Development Board is a dual-processor development board combining an Arduino-compatible ATmega328P microcontroller with an ESP8266 Wi-Fi wireless module featuring 32 Mb flash memory. It includes an on-board CH340G USB-to-TTL converter for easy programming via Micro-USB, and a DIP switch to select between programming the ATmega328P, the ESP8266, or both.
Key Features
Dual MCUs:
• ATmega328P – classic Arduino 8-bit MCU (5 V logic).
• ESP8266 – 32-bit Wi-Fi MCU for wireless connectivity (802.11 b/g/n).Flash Memory: 32 Mb on the ESP8266 for larger firmware and data storage.
USB-to-TTL CH340G: On-board converter simplifies USB connection for power and programming.
Arduino UNO R3 Compatibility: Standard UNO R3 pin layout allows use with Arduino shields and modules.
DIP Switch Mode Selection: Choose whether the USB connection goes to the ATmega328P or the ESP8266 for firmware upload or communication.
Power Input: Via Micro-USB (5 V) or VIN (recommended 6–12 V), with onboard regulator.
GPIO & Interfaces:
• ATmega328P: digital I/O, PWM, UART, SPI, I²C, analog inputs.
• ESP8266: Wi-Fi radio, UART, and additional GPIO.
Typical Uses:
✔ IoT and cloud connectivity – sensor networks sending/receiving data.
✔ Home automation – wireless control of lights, relays, appliances.
✔ Educational prototyping – perfect for Arduino learning and wireless applications.
✔ Web interfaces & APIs – interactive web dashboards via Wi-Fi.
Note: The board uses 5 V logic for the ATmega328P and 3.3 V logic for the ESP8266, so ensure compatible voltage levels for connected peripherals.
