The ESP8266 Wemos family with the Wemos D1 Mini Pro is a true professional among the ESP8266 modules. Building upon the foundation of the ESP8266EX, this iteration boasts an impressive 16MB of memory, a fourfold increase from its predecessor, the Wemos D1 Mini. Crafted for compactness, this new generation incorporates a ceramic antenna, providing an extended line-of-sight range of 90 meters. Noteworthy is the strategic placement of components on the top side of the module, eliminating the conventional heat sink found around the ESP8266 module. This alteration allows for a thicker board, enhancing durability and versatility. For those seeking even greater range, the board seamlessly integrates with the 2.4G Wireless SMA External Antenna included in the kit, amplifying the line-of-sight range to an impressive 150 meters—a 60-meter extension.

Features:

• Utilizes ESP8266EX with 16MB of memory.
• Compact design with a ceramic antenna for a 90m line-of-sight range.

• Dimensions: 34.2 mm x 25.6 mm (thinner than the previous version).
• Weight: 2.5 g.
• External Antenna equipped with an SMA Connector.

Pinout

Additional Notes:

• D0 (GPIO16): No interrupt capability.

• A0 (ADC0): The analog input pin can only read voltages from 0V to 1V. If higher voltages are input, a voltage divider is necessary.
• TX (TXD1): Used for serial debugging output.
• RX (RXD3): Used for serial communication and programming.
• D8 (GPIO15): Must be connected to ground during boot to enable the chip.

Step-by-step guide for first time:
