A development board based on an ESP32-S3 (with Wi-Fi and Bluetooth), which is specially made to use with the Universal Fan Mount for Radiators to easily switch the fans on and off. Unique to this module is the built-in USB PD (USB Power Delivery) trigger. In combination with a USB PD power supply, you can easily set different voltages. This allows you to make the fans run faster (but louder) or slower (but quieter). For example, you can let them run at maximum speed when there is no one in the room for optimal radiator efficiency, or slower and more quiet when there is someone in the same room so that they do not disturb.

In addition to controlling the fans, this module also offers the possibility to connect two NTCs to, for example, monitor the temperature of the inlet and outlet of the radiator. There is also a built-in NTC in the module to detect whether the radiator is on. This works best if the module is mounted directly to the radiator with, for example, two magnetic spacers. Finally, the module also has two Grove connections to connect additional sensors (or actuators).
