NodeMCU ESP8266

Product Description

The NodeMCU ESP8266 V2 is an open-source software and hardware development environment built around an inexpensive System-on-a-Chip (SoC) called the ESP8266. The NodeMCU ESP8266 V2, designed and manufactured by Espressif Systems, contains the essential elements of a computer: CPU, RAM, and networking capabilities (Wi-Fi). It can also run a small real-time operating system (RTOS) and can be programmed using an SDK, making it an excellent choice for Internet of Things (IoT) projects of all kinds Microcontroller ESP8266 (Tensilica 32-bit Xtensa LX106) Flash Memory 4 MB USB Interface CP2102 Operating Voltage 3.3V Input Voltage (via USB) 5V Clock Speed 80 MHz (up to 160 MHz) I/O Pins 17 Analog Input 1 (10-bit ADC) Wi-Fi Standard 802.11 b/g/n Programming Arduino IDE / Lua / MicroPython Dimensions 49mm x 26mm ± 2%
