Q: What is the pin connection description for this module?? ex., is the led pin a backlight and what voltage?

Number Pin Label Description 1 VCC 5V/3.3V power input 2 GND Ground 3 CS LCD chip select signal, low level enable 4 RESET LCD reset signal, low level reset 5 DC/RS LCD register / data selection signal, high level: register, low level: data 6 SDI(MOSI) SPI bus write data signal 7 SCK SPI bus clock signal 8 LED Backlight control, high level lighting, if not controlled, connect 3.3V always bright 9 SDO(MISO) SPI bus read data signal, if you do not need to the read function, you can not connect it (The following is the touch screen signal line wiring, if you do not need to touch function or the module itself does not have touch function, you can not connect them) 10 T_CLK Touch SPI bus clock signal 11 T_CS Touch screen chip select signal, low level enable 12 T_DIN Touch SPI bus input 13 T_DO Touch SPI bus output 14 T_IRQ Touch screen interrupt signal, low level when touch is detected

Q: Does anyone have an arduino example code running with this 3.2" spi display ? - i tried adafruit, ucglib, tft_espi in two displays and none worked.

It works fine for me with an ESP8266 or ESP32. I couldn't get touch to work on the ESP8266 because of lack of output pins. I used TFT_eSPI for the picture and touch. Use Bodners examples.

Q: There is conflicting information in the description. 3.5 in with 480x320 is not a 9341. What is this display's proper description??

I'm not an authority here, but I think that you are correct about the conflict.... ILI9341 is 320x240, and ILI9488 is 480x320. While the main description says ILI9341, one of the pics for this model does identify it as IC Driver ILI9488. perhaps the seller will update the incorrect information. FWIW, good price for this display, and includes touch ..

Q: Is there any way to control brightness of the backlight?

You can drive the 'LED' pin with a PWM signal from a GPIO. The duty cycle of the PWM signal will be proportional to the brightness, just like controlling the brightness of an LED (there are a number of Raspberry Pi and Arduino examples of doing that).
