Dear customer,

thank you for purchasing our product. Please find our instructions below.

Pin Configuration

dtoverlay=w1-gpio,gpiopin=4

sudo nano /boot/config.txt

The LinkerKit module needs to be connected to
the digital-port 4. The appropriate LinkerKit slot
is: [ D4 | D5 | V | G ]

Usage notes

Please note that our LK-Temp2 is used with the build-in pull-up resistor. Therefore, a special library is
necessary which you can find on our LinkerKit website.
An adjusted code is also needed fort he Raspberry Pi but the use of your code-example is sufficient.

If you intend to use multiple sensors, or a sensor with a length of multiple meters, the build-in pull­up resistor is not sufficient anymore.
In this case an external pull-up resistor of 4,7kΩ needs to be connected between the yellow signal-
cable and the red voltage-cable.

Codeexample Raspberry Pi

To allow the communication of the sensors measurement data, the specific configuration has tob e

enabled first. Therefore, add the following line to the "/boot/config.txt" file:
