The ESP8266 D1 Mini Controller is an Internet of Things Development Board. It is a little WIFI board based on the ESP8266. There are 11 digital input/output pins with interrupt/PWM/I2C/one-wire functionality on all of them (except D0) 1 analogue input (maximum 3.3V input) and a Micro USB port. The Wemos D1 Mini is an excellent board for creating WiFi-based Internet of Things projects. It uses ESP8266 Wi-Fi Board (SoC) for IoT applications. It is simple to programe through USB and does not require a separate programmer. It is compatible with Arduino IDE and NodeMCU firmware Chip: ESP-8266EX Compatible with Arduino IDE Compatible NodeMCU firmware GPIO pins: 11 1 pin ADC (0 V to 3.3 V) Max Input Voltage: 24 V Operating Frequency: 80 / 160 MHz Flash Memory: 4MB I2C interface Size: 34.2 x 25.6 mm
