Fan Module CY3210-ExpressDK and CY3210-FanMod Using the on-board 3-wire, speed controllable, 5V external FET driven fan Overview: The Fan Module connects to the CY3210-ExpressDK main board to allow easy PSoC development with fan control and temperature measurement. 1) Select appropriate PSoC Express output device: Fan >> Brushless DC >> Speed Control >> External Drive FET >> 5V 2-/3-Wire. 2) Verify physical connection (on-board fan to terminal block). Fan Control Features: • Control an on-board 3wire, speed controllable, 5V external FET driven fan • Control an off-board attached 2, 3, or 4-wire fan *Set Switch 2 to 5V Temperature Measurement Features: Attaching an off-board 4-wire, speed controllable, 12V integrated FET driven fan • On-board LM20 • On-board Thermister • Two different topologies for on-board Diode Sensing 1) Select appropriate PSoC Express output device:: Fan >> Brushless DC >> Speed Control >> Integrated Drive >> 12V 4-Wire. 2) Connect off-board fan to terminal block. Back of module includes Module Port routing info and explanation of switch settings *Set Switch 2 to 12V Using the LM20 1) Select appropriate PSoC Express input device: Temperature >> Integrated Circuits >> LM20 -55 to +130C. 2) Set Switch 1 to LM20. (LM20 Vout available on S0). Using the Thermistor 1) Select appropriate PSoC Express input device: Temperature >> Thermistor Temp Sensor. 2) Web: www.cypress.com Support: www.cypress.com/support/ US: 800.669.0557 Intl: 425.787.4814 Set Switch 1 to LM20 • Vcc available on S1 • VTherm available on S2 • GND available on S3 Diode Sensor Topologies The Diode Sensor will be supported in future releases of PSoC Express.
