Frequently Asked Questions (FAQ)

Q: Why is it necessary to use a logic level converter with the display?
A: The display operates at a logic level of 3.3V, while Arduino/Raspberry Pi operates at a logic level of 5V, using a logic level converter prevents damage to the display.
Q: Can I use other voltage translators instead of KY-051 with the display?
A: While we recommend using the KY-051 Voltage Translator from Joy-IT, you may use other compatible voltage translators ensuring they match the required logic levels.

GENERAL INFORMATION

Dear Customer,
thank you for choosing our product. In the following, we will show you what to pay attention to during commissioning and use.
If you encounter any unexpected problems during use, please feel free to contact us.
The display can be used with many common developer boards such as Raspberry Pi or Arduino, for example, to display measured values or measured value graphics directly on the microcontroller or single-board computer.

DIFFERENCES BETWEEN THE REVISIONS

This product has a new revision that replaces the previous revision. These changes include the pin out, the LED and the silkscreen.
Below you can see 2 drawings of the different revisions.

USE WITH AN ARDUINO

Connecting the display (REV 1)
Connect the display as shown in the following picture or table to the pins of the “A-side” of your Voltage Translator and then from the “B-side” of the Voltage Translator to your Arduino.
Here we recommend the KY-051 Voltage Translator from Joy-IT.

It is necessary to use a logic level converter, because the display has a 3.3 V logic level, while the Arduino has a 5 V logic level. Not doing so may cause damage to the display.
