LCD 16x2 basi character supply confusing spec

Development Boards Arduino

Hi does anyone know if this product, LCD-09053 from sparkfun will work with 5V output supply from the Uno?

I know that the spec on the product says 3.3V and it works with that but I wonder if I can hookup the 5V without damaging anything.

Here is the spec sheet. ADM1602K-Fsy-FBS-3.3V

However if you see page 4 of the spec it says it can handle Power voltage up to max of 7.0V.

Page 6 then says 3.3V

Then there is the second spec sheet at Sparkfun for ST7066. now this one says

low power operation input from 2.7V to 5.5V, and wide rang LCD driver power 3 to 11V.

Pg 19 also indicate that Vcc can be up to 4.5V.

Then pg 23 shows max absolute rating of .3 to 7V of power supply voltage and LCD driver Volt of .3 to 13V

and for a arduino uno newbie like me this is confusing.

I don’t want to damage my board nor the LCD.

Can anyone help me to tell what is the difference between power supply voltage and LCD driver voltage

and

whether I can push the voltages to 5V.

I am using the adafruit basic character LCD tutorial for connection and the programs by the way.

Thanks.

The board has an LCD display that is specified for 3.3 V and a controller chip that works from 2.7 - 5.5 V. The combination might work at 5 V, but you are taking a chance that the display could be damaged or destroyed.

According to the LCD Datasheet, the max input is 3.5V. So no, I wouldn’t power it with the Arduino. You could set up a voltage divider with resistors to get it down to 3.3V.

And your link to the datasheet you think posted is broke.

Nice double post. I answered your other one.

Pretty much what jremington said.

Thanks. I’ll keep it at 3.3V then.
