ESP32 ESP-32S 30P NodeMCU Development Board Wireless WiFi (Micro USB)

The ESP32 ESP-32S 30P NodeMCU Development Board is a versatile wireless microcontroller platform designed for IoT, robotics, automation and embedded applications. It combines substantial processing capability with built-in wireless connectivity, making it possible to develop connected devices without requiring separate WiFi or Bluetooth modules.

Powerful Dual-Core Processing

The ESP32 platform features a dual-core processor capable of operating at speeds of up to 240MHz. This provides sufficient processing capability for demanding embedded applications, wireless communication, sensor processing, web interfaces and real-time control tasks.

The platform also supports RTOS-based development, making it suitable for applications where multiple tasks need to run concurrently.

Built-in WiFi & Bluetooth

The board supports 2.4GHz 802.11 b/g/n WiFi, with wireless speeds of up to 150Mbps under suitable conditions. It also supports both Classic Bluetooth and Bluetooth Low Energy (BLE).

The ESP32 can operate in Station (STA), Access Point (AP), or STA + AP mode, providing flexibility for IoT devices, local wireless networks and direct device-to-device communication.

Extensive Peripheral Interfaces

The ESP32 provides a wide selection of hardware interfaces, including:

• UART
• GPIO
• ADC
• DAC
• PWM
• SPI
• SDIO
• SD Card
• I2C
• I2S

This makes the board suitable for connecting sensors, displays, motors, storage devices, communication modules and other peripherals.

Low-Power Operation

The ESP32 supports multiple sleep modes for battery-powered applications. With appropriate firmware and power-management configuration, the ESP32 chip can achieve very low sleep current, making it suitable for wireless sensor nodes, remote monitoring devices and portable IoT products.

OTA / FOTA Firmware Updates

The platform supports remote firmware updating, allowing compatible IoT devices to receive software updates over a network without requiring physical access to the programming interface. This is particularly useful for deployed sensor nodes, smart devices and connected automation systems.

Integrated Networking

The integrated LwIP TCP/IP protocol stack provides networking functionality for Internet-connected applications. Developers can create web servers, dashboards, remote monitoring systems, APIs and other network-enabled applications directly on the ESP32.

Breadboard-Friendly Development

The NodeMCU-style board is designed for convenient prototyping and can be used with standard breadboards and jumper wires. Its compact layout makes it suitable for development work as well as integration into custom IoT and robotics prototypes.

Power & Safety Considerations

The ESP32-WROOM-32S operates at approximately 3.3V, and its GPIO pins are designed for 3.3V logic. Do not connect 5V logic signals directly to ESP32 GPIO pins unless an appropriate level-shifting solution is used.

When powering the board through its USB interface, the onboard power circuitry can provide the required regulated voltage. When supplying power directly, use a clean and stable supply within the board's specified voltage range.

Avoid reverse polarity, short circuits, excessive voltage, and incorrect GPIO connections, as these can permanently damage the ESP32 module.
