Smart Fan Cooling Control Board for Raspberry Pi

Description For more advanced raspberry pi 3 (RPI), it is very necessary to add cooling solution to keep the temperature down. This is a addon board with small fan on it, turn ON control by: GPIO 12 On board temperatue sensor LM75 hardware alarm (pre-programmed) trigger No not support PWM control, only ON/OFF On board Power Supply On board DC-DC power module and standard DC 5.5-2.1 jack, allow 5.6-14V to 5V 4A output. Power supply for raspberry pi, fan,  and can also output to cable terminal for other devices. On board power LED, and power ON/OFF switch. Output Power supply Output to 3.96mm cable terminal, connector and socket can be seperated. Inrush current protection on output terminal Output power supply indicator LED Sensor: On board LM75 temperature sensor Fan: DC 5V 3mm 3007 small common fan. Documentation please see on this page.
