How many total pins are there in NodeMCU?
17 GPIO pins
GPIO Pins. ESP8266 NodeMCU has 17 GPIO pins which can be assigned to various functions such as I2C, I2S, UART, PWM, IR Remote Control, LED Light and Button programmatically. Each digital enabled GPIO can be configured to internal pull-up or pull-down, or set to high impedance.
Is NodeMCU same as Arduino?
NodeMCU is a microcontroller development board with wifi capability. It uses an ESP8266 microcontroller chip. Whereas Arduino UNO uses an ATMega328P microcontroller. Besides the chip, it contains other elements such as crystal oscillator, voltage regulator, etc.
What is the Wi-Fi range of NodeMCU?
NodeMCU Technical Specifications
| Official NodeMCU | NodeMCU Carrier Board | |
|---|---|---|
| ADC Range | 0-3.3V | 0-3.3V |
| UART/SPI/I2C | 1 / 1 / 1 | 1 / 1 / 1 |
| WiFi Built-In | 802.11 b/g/n | 802.11 b/g/n |

Can we supply 5V to NodeMCU?
Power Required By NodeMCU Nodemcu operates at 5v & 3.3V. For 3.3V there is already an LDO voltage regulator to keep the voltage steady at 3.3V. NodeMCU can be powered using Micro USB jack and VIN pin (External Supply Pin).
Why is NodeMCU cheaper than Arduino?
Cheaper: NodeMCU is an ESP8266 chip-based microcontroller development board, which is very cheap as compared to Arduino UNO. Breadboard-friendly and compact: The NodeMCU can be easily inserted into a breadboard and test various circuit designs. Whereas Arduino UNO cannot be fit into the Breadboard.
Is NodeMCU an Arduino?
NODEMCU is a development board with ESP8266 and a firmware with the same name. Similarly the Arduino Uno is a microcontroller board based on 8 bit ATmega328P microcontroller.
Can I power NodeMCU with 12v?
Yes you can connect a 12v charger to one battery and charge it, then move it to the other and charge it, without disconnecting them from the series.
