WeMos D1 Mini Type-C

The WeMos D1 Mini Type-C (specifically the V4.0.0) is an updated version of the popular ESP8266-based development board, replacing the older micro-USB port with a more durable and reversible USB-C connector. It remains a compact, WiFi-enabled platform ideal for IoT projects and is fully compatible with the existing ecosystem of D1 Mini.

Technical Specifications:

• Microcontroller: ESP8266EX 32-bit processor with a clock speed of 80MHz or 160MHz.
• Memory: 4MB (32M bit) onboard Flash memory.
• Operating Voltage: 3.3V logic level (regulated internally from the 5V USB-C input).
• I/O Pins: 11 digital I/O pins supporting PWM, I2C, and UART (except D0), and 1 analog input with a 3.2V maximum.
• Dimensions: Ultra-compact footprint of approximately 34.2mm x 25.6mm.
• USB Interface: USB Type-C port using the CH340G USB-to-serial converter. 

Features:

• Enhanced Connectivity: The V4.0.0 model includes a dedicated I2C port (JST-SH 4-pin) for easier connection to sensors without soldering.
• Software Support: Fully compatible with the Arduino IDE, MicroPython, NodeMCU, and Lua.
• Shield Ecosystem: Designed to work seamlessly with the original stackable, including relays, OLED displays, and various sensor modules.

Usage:

1. Connect the WeMos D1 WiFi UNO to your computer via the USB interface.
2. Install the necessary drivers and Arduino IDE with the ESP8266 board support package.
3. Write and upload your code using the Arduino IDE, leveraging the WiFi capabilities to connect to networks or web services.
4. Use the digital I/O pins, analog input, and onboard LED in your projects according to your needs.
5. Monitor and debug your project using serial output or other communication methods.

Caution:

• Ensure proper USB connection and avoid overvoltage to prevent damage.
• Follow the WiFi module’s usage guidelines for optimal performance and connectivity.
• Handle with care to avoid damage to the onboard components.
