Witty Cloud ESP8266 ESP-12F Development Board w/ LDR & RGB LED

Connect the included CH340G programmer board via micro USB to your computer. Install the CH340 driver if needed. Use the Arduino IDE with the ESP8266 board package installed, select 'NodeMCU 1.0 (ESP-12E Module)' as your board, set the upload speed to 115200 baud, and press the Flash button on the programmer before uploading your sketch. The board will then run your code on the ESP-12F module.

The onboard Light Dependent Resistor (LDR) is connected to the ADC pin (A0) of the ESP8266. In your code, use analogRead(A0) to get a value between 0 and 1023 corresponding to light intensity. Lower values indicate darkness, higher values indicate brightness. No external wiring is required, making it ideal for ambient light detection in automation projects.

Yes, the lower board containing the CH340G USB-to-UART converter can be detached and used independently. It provides TX, RX, VCC (3.3V or 5V selectable via a jumper), and GND pins. You can use it to program other ESP modules like the ESP-01 or any 3.3V/5V serial device by connecting the appropriate pins and using flash tools like esptool.py or the Arduino IDE's serial programmer.

The integrated WS2812 addressable RGB LED is connected to GPIO 15 (data line). You must use libraries like Adafruit_NeoPixel or FastLED to control it. Note that GPIO 15 has a pull-down resistor at boot, so ensure your code initializes the LED after boot. The LED provides visual feedback without requiring external components.
