NodeMCU can be powered using a Micro USB jack and VIN pin (External Supply Pin). Its high processing power with in-built Wi-Fi / Bluetooth and Deep Sleep Operating features make it ideal for IoT projects. NodeMCU has 128 KB RAM and 4MB of Flash memory to store data and programs. This microprocessor supports RTOS and operates at 80MHz to 160 MHz adjustable clock frequency. The NodeMCU ESP8266 development board comes with the ESP-12E module containing the ESP8266 chip having Tensilica Xtensa 32-bit LX106 RISC microprocessor. Note: Complete technical information can be found in the NodeMCU ESP8266 Datasheet, linked at the bottom of this page.Īrduino, Raspberry Pi, PIC Development Board, AVR Development Board, MSP430 Launchpad, Intel Edison, Beagle Bone Small Sized module to fit smartly inside your IoT projects.
USB-TTL based on CP2102 is included onboard, Enabling Plug n Play.Microcontroller: Tensilica 32-bit RISC CPU Xtensa LX106.NodeMCU ESP8266 Specifications & Features NodeMCU has I2C functionality support but due to the internal functionality of these pins, you have to find which pin is I2C. UART1 is used to upload the firmware/program. NodeMCU has two UART interfaces, UART0 (RXD0 & TXD0) and UART1 (RXD1 & TXD1). NodeMCU has four pins available for SPI communication. NodeMCU has 16 general purpose input-output pins on its board
Used to measure analog voltage in the range of 0-3.3V The pin and the button resets the microcontroller Micro-USB: NodeMCU can be powered through the USB portģ.3V: Regulated 3.3V can be supplied to this pin to power the board NodeMCU Development Board Pinout Configuration NodeMCU is an open-source Lua based firmware and development board specially targeted for IoT based Applications. It includes firmware that runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module.
