I/O voltage of 1743

[shibinvarghese]

Hi Team,
I am using 1743 in one of my projects.
I am planning to provide a 5V supply as the input (Vin) directly from a USB.
What is the maximum voltage at the Vin pin?.
Also, what will be the I/O voltage of SPI?.
I am planning to use a 3.3V MCU as the host.
SPI will be the communication protocol od the display module with the host
I am using TSC2004IRTJT to convert the analog youch data to I2C format.
My device is a battery-operated one, so what is the power consumption of the module when working?.
What is the purpose of IM0-3 pins?.
Is there any reference design available for the same?.

from the product page the bottom of the board suggest 3-5v as the input voltage
closing IM1, IM2 and IM3 sets SPI mode

Hi Marshaj,
Thank you for your reply.
I will make myself clear to you.
The module 1743 is Arduino compatible, so its input/output logic is 5V, I am using a 3.3V microcontroller so do I need a level translator to convert the 5V logic of the display module to be compatible with the 3.3V of the controller?. (I will be running the Vin pin at 5V)
Also is there any technical data available for the module to know the power consumption and all?.

It also states about the interfaces
"Both are 3-5V compliant with high-speed level shifters so you can use with any microcontroller."

I don't know about the power consumption.

The ILI9341 TFT driver uses 3.3V, which comes from an LP298x voltage regulator built into the breakout.

The regulator can handle input voltages up to 16V, but we advise against using any supply voltage higher than 5V. Above that, you lose more power in the voltage regulator than the display itself uses.

The TFT itself uses very little current, but the LED backlight uses about 120mA.
