The ESP8266/ESP-12F Module/Serial WIFI Witty Cloud Development Board + MINI NodeMCU is a cost-effective and compact WiFi transceiver, ideal for home automation and IoT applications. It can directly communicate with your WiFi router via UART MCU (Rx, Tx), making it a great alternative to the NRF24L01.
Features:
ESP-12 Module:
One of the most comprehensive modules in the ESP family, offering the most pin availability.
Programmable with the Arduino IDE or LUA as NodeMCU.
Includes an onboard LDR and WS2812 LED for project development.
Programming and Connectivity:
Comes with a CH340 micro USB module for easy programming.
Highly integrated chip with built-in antenna and power management.
Functionality:
Energy Efficiency:
VoIP with quick switching between sleep/wake modes.
Low-power operation with adaptive radio bias and front-end signal processing.
Development Kit:
Known as the “Witty Cloud,” this development kit is simple and cost-effective for IoT projects.
Does not require deep network knowledge; basic C programming skills suffice.
Supports EMC’s cloud SDK for quick secondary development.
The demo board can control RGB lights via a mobile app and display environmental brightness using the photosensitive resistor.
Hardware Description:
Stacked PCB Design:
The module consists of two stacked PCB boards connected by 8-pin headers.
The upper board includes the ESP-12F module, an RGB LED, an LDR, a button, a micro USB port, and a 3.3V voltage regulator.
The lower board contains the CH340G USB-to-UART module, providing a connection to a computer for programming and debugging.
Additional buttons for reset (RST) and flash, along with a micro USB port.
Usage:
Standalone Operation:
Once programmed, the main Witty board can function independently.
The bottom CH340 board can be detached and used as a standalone USB-to-UART programmer for other modules.
Programming Options:
Arduino IDE and NodeMCU:
Compatible with both Arduino IDE and LUA for NodeMCU, offering flexibility in development environments.
Package Includes:
1 x ESP8266 / ESP-12F / Serial WIFI Witty cloud Development Board Module
