Description
The Wemos D1 mini Pro is really the Pro in the ESP8266 Wemos family. as always built around the ESP8266EX but this time with 4 times more memory (16Mbytes) than the Wemos D1 mini. Wemos headed on compactness with this new generation of ESP8266 modules by using a ceramic antenna which gives you a 90m of range in the line of sight. the components are soldered on the top side of the module. Note the disappearance of the heat sink usually appears around the ESP8266 module, which gives the ability for a thicker board. and if the range is not enough you can connect the board to the 2.4G Wireless SMA External Antenna you can find within this Kit will give you a 150m of range in the line of sight which total is of 60m more!!.
the board uses the CP2104 as a Serial converter so you can get the driver for it by clicking here:
The number and characteristics of the inputs/outputs are always the same and the number 11 (more an analog input). The main technical features of the Pro:
11 digital I/O
- Interruption/PWM/I2C/one-wire: available on all pins except the D0
- 1 analog input, limited to a voltage of 3.2V Max
- 16M bytes (128 M bit) memory Flash
- IPEX connector for WiFi antenna external
- Integrated ceramic antenna
- New CP2104 serial/USB converter
- CPU frequency : 80 MHz / 160 MHz
- Dimensions: 34.2 mm x 25.6 mm (thinner than the previous version)
- Weight: 2, 5 g
- External Antenna comes with SMA Connector

the External antenna can give us more range so you can see the difference in this video:
