ESP8266/ ESP-12F Module/ Serial WIFI Witty Cloud Development Board + MINI nodeMCU

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.
