The connector on the display is it a JST PH series like the S4B-PH-SM4-TB?

Dear DFRobot and users. I have just connected a DFR0555 (LCD1602Module V1.1) to my PCB. I am able to write text to the display @ 7Bit address 0x3E, however the text is barely visible as I am not able to turn the backlight on. I am accessing the backlight through I2C 7Bit address 0x6B.
VCC and I2C logic to the LCD and Backlight module is 3.3V.
Attached is a screenshot from the data aquired from my Saleae Logic analyzer. All seems to be fine...
Any ideas from any smart people here? :-D
JaneYu It is the address of the back light port that changed. In display V1.0 the address was 0x60 and now (V1.1) it is 0x6B.
JaneYu Hi, I'm gonna using this as DIY display. Anybody know the name of connector(PCB header)?
JaneYu I soldered this 2.54mm header to my PCB. This fits to the LCD cable for the DFR0555 I received. https://uploads.disquscdn.c...
Yes, it's work with 1.0 but not with 1.1
The text is displayed but without backlight
I have tried with 5 modules in 1.1 with same result
JaneYu Hi, any body knows the changes between pcb v1.0 and pcb v1.1 ?
With 1.1, the backlight doesn't work :(
JaneYu Hi, the wiki for this product is unavailable on the website and I am having difficulty using this product, please help.
JaneYu I am not sure if the Arduino is in a dead wait state. You can add the LED BLINK code to confirm the lights on the board are always on or not.
What hardware do you use, except this LCD? In fact, I want to reproduce this question. Could you tell me what is going on in my environment?
JaneYu Hi, this LCD is for arduino but I use it in a different platform - TI DSP C2000. DSP is used primarily to control power electronics circuit, that's why there is noisy EMI. It also drives the LCD to display system parameters. I don't understand your last sentence.
