PowerNode WiFi Kit – ESP8266 with 18650 Battery

Description

Product Overview

The PowerNode WiFi Kit is a complete, self-contained IoT development platform that combines the popular ESP8266 WiFi module with an integrated 18650 lithium-ion battery holder and charging circuit. This all-in-one solution eliminates the need for external power supplies or complex wiring, allowing you to build truly portable, battery-powered IoT devices with ease .

At the heart of this kit is the powerful ESP8266EX chip—a 32-bit microcontroller with integrated Wi-Fi (802.11 b/g/n), a full TCP/IP stack, and ample processing power for most IoT applications . The module comes pre-flashed with user-friendly firmware (such as NodeMCU or AT command set), making it accessible for beginners while remaining powerful enough for advanced users .

The integrated 18650 battery holder allows you to power your projects with a single rechargeable lithium-ion cell—the same type used in many laptops, flashlights, and power banks. The onboard charging circuit (via microUSB) lets you recharge the battery without removing it, while the built-in power switch prevents parasitic drain when the system is idle . This makes the PowerNode WiFi Kit the ideal choice for remote sensors, portable data loggers, wireless control systems, and any project that needs to operate away from a wall outlet.

Whether you’re building a wireless weather station, a battery-powered security camera, a remote soil moisture sensor, or a smart home controller, the PowerNode WiFi Kit provides a compact, ready-to-use platform that gets your project up and running quickly.

Key Features

• All-in-One IoT Platform: Combines an ESP8266 WiFi module, 18650 battery holder, charging circuit, and voltage regulation into a single, compact board.

• Integrated 18650 Battery Support: Designed to work with a single 18650 lithium-ion battery (not included), providing a high-capacity, rechargeable power source for portable projects.

• Onboard Battery Charging: Features a microUSB port for charging the 18650 battery directly on the board. Charging status is indicated by an onboard LED.

• Efficient Power Management: Includes a dedicated power switch to completely disconnect the battery, preventing parasitic drain when the system is not in use. A voltage regulator ensures stable 3.3V output for the ESP8266 and any connected peripherals.

• ESP8266-Based WiFi Connectivity: Powered by the widely-supported ESP8266EX chip, providing 802.11 b/g/n Wi-Fi with a full TCP/IP stack. Perfect for connecting to home networks, cloud services (AWS IoT, Blynk, ThingSpeak), or creating your own access point.

• Versatile Firmware Options: Ships with AT command firmware, NodeMCU (Lua), or can be easily re-flashed with MicroPython, Arduino (via Arduino IDE), or custom firmware using the ESP8266 SDK.

• Easy Programming: Features a USB-to-serial interface (CH340 or CP2102) for direct programming via microUSB. No additional programmers or adapters are required.

• Multiple I/O Interfaces: Exposes digital I/O pins, ADC input, UART, SPI, and I2C interfaces, allowing connection to a wide variety of sensors, relays, displays, and actuators.

• Low Power Consumption: Supports deep sleep modes, enabling battery-powered operation for months or even years in low-duty-cycle applications.

• Compact and Ready-to-Use: The board is designed to be used standalone or mounted in an enclosure. All components are pre-soldered—no soldering required to get started.
