Esp-Wroom-02 ESP8266 Mini WiFi Nodemcu Module 18650 Battery
€18.00
Tax included
ESP-WROOM-02 NodeMCU development board (ESP8266) with integrated 18650 battery support. Up to 17 hours runtime with a 3000 mAh cell.
Description:
The development board integrates a management system for an 18650 battery. With a standard LG 3000 mAh battery, runtime can reach 17 hours.
What is it?
You can call it a "WiFi battery." This module simplifies adding an 18650 battery to your ESP8266 projects.
Why use it?
When building ESP8266 projects, power supply is often a challenge. This miniature board solves this problem. An LG 3000 mAh battery allows the ESP8266 to run for 17 hours or more.
What makes it special?
· Based on NodeMCU.
· Integrated 18650 charging system.
· Status LED (green = full, red = charging). Charging and operation can occur simultaneously.
· 1 power switch.
· 1 SMT connector available for sleep mode.
· 1 additional programmable LED (via GPIO16 [D0]).
· Charge current: 0.5 A.
· Output current: 1 A.
· Overcharge protection.
· Over-discharge protection.
· 10 digital pins supporting read/write, interrupts, PWM, I2C (except D0).
· 1 analog input (observe polarity + -).
If the battery is inserted in the wrong direction, the charging chip will be destroyed.
Note: This product does not include an 18650 battery.
Package included:
1 x WeMos D1 Esp-Wroom-02 Motherboard, Mini-WiFi Nodemcu Module ESP8266 with 18650 Battery Support
