01 — About

What it does

The ESP32 WROOM Nodemcu 38 Pin is an extended version of the ESP32 devkit with 38 pins and a NodeMCU form factor. It features dual-core processing, integrated WiFi and Bluetooth, and expanded GPIO access for demanding IoT and automation projects.

Key features

  • Dual-core Xtensa LX6 32-bit processor up to 240MHz
  • 38 GPIO pins in NodeMCU form factor for expanded connectivity
  • Built-in WiFi 802.11 b/g/n for wireless connectivity
  • Bluetooth 4.2/BLE support for wireless peripherals
  • Ultra-low power modes for battery-operated devices
  • 4MB flash memory for program and data storage
  • Rich peripheral interfaces including SPI, I2C, UART, ADC, DAC, PWM

Good to know

  • All GPIO pins use 3.3V logic – use level shifters for 5V devices
  • Install ESP32 board package in Arduino IDE before use
  • 38-pin variant offers more I/O than standard 30-pin version
  • Some pins have boot-mode functions – consult pinout diagram
  • USB-C or Micro-USB connector depending on manufacturer
