The PiCoolFan is an Advanced Cooling Fan System for the Raspberry Pi, that offers total temperature control and includes a Real Time Clock! The PiCoolFan is suitable for all Raspberry Pi users whose board reaches a high temperature, for whatever reason. There is no need for any additional cabling or Power Supply, as the PiCoolFan is powered via the GPIO pins; just insert the PiCoolFan controller on top of the P1 connector of your Raspberry Pi.
The PiCoolFan is equipped with an embedded temperature measurement system that continuously checks the Raspberry Pi PCB temperature with a dedicated sensor and, according to the measured temperature, the PiCoolFan micro controller starts, stops, or regulates the rotational speed of the embedded micro-fan. Thanks to the Air Distribution Plate, the PiCoolFan cools not only the microprocessor on the Raspberry Pi board but all the heat-generating devices, as well as the whole Raspberry Pi PCB.
The embedded microcontroller is easily accessible by the user through the I2Cinterface and allows reading of the measured temperature, setting of temperature threshold, as well as starting/stopping the embedded micro fan. In addition the PiCoolFan offers on the same PCB a battery backed Real Time Clock and Real Time Powering Voltage Monitoring.
