Automatic fan control module for Raspberry Pi with 5-V port on top and additional contacts for the I2C interface Control your Raspberry Pi's fan with this compact module. Many fans run constantly and at full speed. Simply connect this module and you can set a target temperature for the fan to start working using Raspian. The data sheet provided includes comprehensive installation instructions. In addition to the connections for a fan, the module features two pins for the 5-V supply routed to the outside, so that these remain usable. In contrast to the RPI FAN CONTROL, this product has a second connection, which allows both the pins for I2C communication and the pins for the 3.3-V power supply to be used. https://elecena.pl/product/18879567/hatl02f-raspberry-pi-fan-controller-i2c 2021-06-21 https://elecena.pl/product/18879567/hatl02f-raspberry-pi-fan-controller-i2c 2026-01-15
