ESP8266/ ESP-12F Module/ Serial WiFi Witty Cloud Development Board + Mini NodeMCU

Description:

The ESP8266/ESP-12F WiFi Module (Witty Cloud Development Board + Mini NodeMCU) is an affordable, compact WiFi transceiver that offers an ideal solution for Home Automation and IoT applications. It serves as a great alternative to the NRF24L01, providing direct communication with your WiFi router via UART (Rx, Tx) from an MCU.

The ESP-12F module is one of the most feature-rich in the ESP family, offering a wide range of available pins for versatile project designs. It can be programmed to run standalone using the Arduino IDE or with LUA scripting through NodeMCU. The board comes equipped with an LDR (Light Dependent Resistor) and an onboard WS2812 RGB LED, making it ready for various projects. Additionally, it includes a CH340 micro USB module for easy programming.

The ESP8266 chip is highly integrated, incorporating an onboard antenna and power management converter. It is optimized for energy-efficient VoIP applications, with fast switching between sleep and wake modes, adaptive radio bias, and front-end signal processing for low-power operation.

This ESP8266/ESP-12F Module / Serial WiFi Witty Cloud Development Board + Mini NodeMCU is a powerful yet simple cloud-enabled hardware development kit. It’s one of the most cost-effective and easy-to-use IoT development boards available. You don’t need advanced network knowledge or familiarity with TCP/IP—just basic C programming skills and you can quickly develop custom applications using the provided SDK. The included demo board allows mobile phone control of RGB lights, environmental brightness display via the LDR, and remote control of devices via a mobile app (Android or iOS). With minimal code modification, you can develop a fully functional system in under an hour.

Known as Witty Cloud, this ESP8266-based module consists of two stacked PCBs connected by 8-pin headers.

The upper board features the ESP-12F module, which contains the ESP8266 Wi-Fi microcontroller, an RGB LED, LDR, a button, a micro USB port, and a 3.3V voltage regulator.
The lower board includes the CH340G USB-to-UART module, which allows connection to a computer for programming the flash or viewing debug messages. Additional buttons for Reset and Flash operations are also included.

The Witty Cloud board can operate independently once the firmware is developed for your specific project. The CH340 USB-to-UART board can be detached and used as a standalone tool to program other modules. The module is compatible with the Arduino IDE or LUA scripting (via NodeMCU) for flexible programming options.

Note:

• User push button connected to GPIO4
• Bottom board (with CH340G) can be separated and used as a USB-to-UART stand-alone to program other modules (like ESP-01)
• Two mini USB connectors (one on bottom and top boards) to allow top board to be powered and used independently
• While this board is fully compatible with the NodeMCU firmware, it does not come pre-flashed with it.
• Since we don’t open the original packaging, we don’t get a chance to re-flash it before sending it to you.
• You must reflash it (using the NodeMCU flasher or the Arduino IDE) before you can use it
• ESP-12F module with Espressif ESP8266EX SoC
• Connectivity – WiFi 802.11 b/g/n
• 2x 8-pin headers with GPIOs, VCC, GND, Reset, ADC, and UART
• USB – 2x micro USB port (one for power, one for debugging)
• Photoresistor, RGB LED, three buttons for power, reset, and firmware upgrade

Features:

• LDR Light Sensor on board
• WS2812 LED on board
• 3x tactile buttons (1x in the Witty board and 2x in the CH340 board)
• Micro USB connection for power and/or programming
• Uses latest ESP-12F module with 4M flash and integrated antenna
• Includes CH340G USB-to-UART programmer
• Includes LDR (light dependent resistor a.k.a photoresistor) connected to ESP’s ADC pin
• RGB LED connected to GPIO 12, 13, and 15
• Supports 3 modes: AP, STA, AP+STA
