Wemos D1 Mini Pro With External Antenna

Description

Introduction to Wemos D1 Mini Pro

The Wemos D1 Mini Pro is a compact WiFi development board based on the ESP8266EX microcontroller. Moreover, it combines wireless connectivity with a lightweight design for embedded projects.

In addition, the board features a built-in ceramic antenna. It also includes an external antenna connector. Therefore, users can choose the antenna setup that best suits their project.

Furthermore, the board provides 11 digital input/output pins. These pins support useful functions such as PWM, I2C, interrupt, and one-wire communication. As a result, the board can connect with various sensors and electronic modules.

How the Wemos D1 Mini Pro Works

It operates at 3.3V and uses the ESP8266EX microcontroller. First, users can program the board through its USB-to-UART interface.

Next, the board runs the uploaded firmware and connects to available WiFi networks. Then, developers can use the wireless connection to communicate with sensors, modules, and online services.

Additionally, the board uses a CP2104 USB-to-UART IC. As a result, programming and serial communication become more convenient.

Moreover, the module provides 4MB of Flash memory. Therefore, it offers useful storage capacity for many IoT and wireless applications.
