Immediate Dispatch

The NodeMCU V3 board is based on the single-core ESP8266 (ESP-12) 80MHz microcontroller. It is a WiFi-only IoT Development Board (does not feature Bluetooth), equipped with 4MB Flash Memory, a Type-C port, and the CH340G communication chip. It supports programming via NodeMCU Lua, MicroPython, ESPHome, and the Arduino IDE, featuring a built-in TCP/IP stack for immediate networking. It provides a 30-Pin layout. WARNING: All GPIOs operate strictly at a 3.3V logic level.

Product Details

Technical Specifications and Capabilities of the ESP8266

The ESP8266 microcontroller (32-bit Tensilica architecture) is designed to integrate Wi-Fi connectivity into electronic circuits. It operates either as a standalone processor or as a slave module for other microcontrollers, widely used in telemetry systems, wireless sensors, and IoT devices.

Processor & Memory: Single Core clocked at 80MHz, accompanied by 4MB Flash (25Q32 32Mbit) for firmware storage (e.g., NodeMCU Lua) and OTA updates.
Wireless Connectivity: Supports IEEE 802.11 b/g/n (2.4 GHz) with STA (Station), AP (Access Point), or combined STA + AP operating modes.
USB Interface: Utilizes a Type-C port paired with the CH340G USB-to-TTL serial converter, which may require manual driver installation on certain operating systems.
I/O Interfaces: The 30-Pin form factor provides access to GPIO, PWM, 10-bit ADC, I2C, 1-Wire, and UART interfaces.

Limitations & Usage Warnings

No Bluetooth: This specific chip exclusively supports Wi-Fi. It lacks hardware support for Bluetooth or BLE.
Operating Voltage (3.3V): The GPIO pins are not 5V-tolerant. Interfacing with 5V logic (e.g., older Arduino sensors) requires a Logic Level Converter to prevent hardware damage.

Frequently Asked Questions (Q&A)

Q: Can this be integrated into Home Assistant?
A: Yes. The ESP8266 is fully compatible with ESPHome and Tasmota firmware. It can be programmed over-the-air (OTA) to build custom sensors (temperature, humidity, relays) that communicate locally via Wi-Fi.

Q: What are the power requirements?
A: The board is powered by 5V via the USB Type-C port or the Vin pin. The onboard voltage regulator steps this down to the 3.3V required by the microcontroller.

Suggested Alternatives

If you prefer the CP2102 chip (which is automatically recognized on Mac/Linux without manual driver installation): Check out the ESP8266 NodeMcu V2 CP2102 Type-C.
If your project requires Bluetooth (BLE) or a dual-core processor: Consider the ESP32 Development Board (DevKit V1).
