D1 Pro Mini ESP8266 with External Antenna

$15.95
SKU 54881027

Now available from PMD Way is the powerful and compact D1 Pro Mini ESP8266 with External Antenna. These boards support a wide range of programming types such as Arduino, BASIC, microPython, NodeMCU, and whatever else the ESP8266 community comes up with. 

They're a great way to get into the Internet of Things, experiment with various languages, build WiFi-enabled Arduino projects, or harness the powerful onboard ESP8266 for your own devices.

Board has 16MB of flash memory fitted. However some development environments may not be able to access more than 4MB. 

Inline header pins and sockets are included but not soldered to the board. Pins have standard 0.1"/2.54mm spacing and are ideal for use in solderless breadboards.

This board also includes an antenna cable around 20cm in length and an external WiFi antenna.

Furthermore, we offer all the optional LoLin expansion boards from prototyping PCBs to sensors, displays and more. 

Features:

  • 11 digital input/output pins, all pins have interrupt/PWM/I2C/1-wire support (except D0)
  • 1 analog input (3.2V max input)
  • micro USB interface for power and code upload
  • CP2104 USB interface
  • Board size - 25.6 x 34.2 mm
