WeMos D1 Mini ESP8266-12F Module Arduino IoT
The development board allows you to integrate the Wi-Fi module (ESP8266), known for its ease of use and considerable possibilities, in projects requiring access to the network, e.g. as part of IoT. The module has 11 digital I / O pins with interrupts, PWM, I2C and 1-Wire. There is also 1 analog input (3.2V max input). The module is programmed via the Micro USB connector. The board is compatible with Arduino, MicroPython, NodeMCU.
WeMos D1 MINI module is based on the ESP12 chip and has 11 GPIO pins. Works on the Wifi 802.11 b / g / n standard at 2.4 GHz. This device can be used as a converter for connecting the microcontroller to Wi-Fi or as a separate and independent controller (standalone device). The ESP12 has 4MB of Flash memory. It is possible to program the module using LUA scripts, Arduino IDE and also using AT commands. The board has a soldered CH340 programmer (the driver must be downloaded), as well as a Micro USB connector, so we do not need any additional elements to program the module. The set includes 3 types of goldpin header connectors for soldering: 2x goldpin connector, 2x goldpin short socket, 2x goldpin extension socket.
