This module is a fan speed controler with a temperature sensor.

It is compatible with 12V and 24V DC power.

It can be used to regule the noise of your printer, by sticking the probe to the heatsink of the motor stepper (X or Y).

With the 2 potensiometers you can setup the temperature of starting.

Assembly choice: The SMT components will be assembled. You can choose to buy the PCBA fully assembled or partially assembled, in which case only the components with legs will need to be assembled.

In all the cases, you will need to solder a cable for the sensor, and to glue it (with silicone adhesive paste K-5203 for exemple, or hot glue) on the heatsink of the stepper.

With choosing the kit option, you can solder the potensiometers on the rear side of the PCB :

Connections :

Mounting inside the printer (on TMC2208):

Of course, the module can be used for another machine (PC, CNC, etc.)

Here is the operating result :
