Description: 1. Overview: ESP32 (38 Pin) WiFi + Bluetooth NodeMCU-32 Development Boards are a set of 25 microcontrollers, based on the ESP32-WROOM-32 chipset, suitable for building IoT projects with WiFi and Bluetooth connectivity. 2. Features: Each board comes with an integrated ESP32 system-on-chip (SoC), WiFi, Bluetooth (BLE) capabilities, 38 GPIO pins, 11 touch pads, 2 UARTs, 2 I2C interfaces, 1 SPI interface, and 10-bit ADC. 3. Connectivity: These development boards offer dual wireless connectivity with WiFi supporting both 2.4GHz and 5GHz bands and Bluetooth (BLE) for low energy applications. 4. Programming: ESP32 microcontrollers can be programmed using the Arduino IDE, MicroPython, or ESP-IDF frameworks, allowing users to choose their preferred programming language and development environment. 5. Powerful Processor: ESP32's Xtensa dual-core 32-bit processor operates at a clock frequency of up to 240 MHz, making it ideal for handling complex IoT projects while maintaining low power cons
