2. Soldering the headers Before using your click board , make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 4. Essential features FAN click 2 3 Fan click supports PWM speeds from 9.5Hz to 29 KHz, in four programmable frequency bands. The control algorithms and the clock inside the circuit allow you to regulate the RPM of a given fan with 1% accuracy in the 500-16k RPM range. The TACH pin gives feedback on the fans operation. The IC also incorporates detection of aging fans, and alert on fan stall Turn the board upside down so that Turn the board upward again. Make sure (the fan driver even attempts to fix a stalled the bottom side is facing you upwards. to align the headers so that they are fan while sending the interrupt) These alerts Place shorter pins of the header into the perpendicular to the board, then solder the are sent through the mikroBUS INT pin. appropriate soldering pads. pins carefully. 1. Introduction Fan click carries an EMC2301 controller for powering and regulating the operation of 3. Plugging the board in four-wire fans, which are commonly utilized click as coolers in computers and other electronics. Once you have soldered the headers your The top of the board features two pairs of board is ready to be placed into the desired BOARDS screw terminals with PWM, 5V power supply, mikroBUS socket. Make sure to align the cut www.mikroe.com TACH and GND pins. The communication in the lower-right part of the board with the with the target MCU is done through the markings on the silkscreen at the mikroBUS mikroBUS I2C interface, with an additional socket. If all the pins are aligned Fan click Manual v100 INT pin. Board is designed to use 3.3V power correctly, push the board all the supply, but also works with 5v logic. way into the socket. 01000000897438. Code examples 5. Schematic Once you have done all the necessary preparations, its time to get your click board up and running. We have provided examples for mikroC , mikroBasic and mikroPascal compilers on our Libstock website. Just download them and you are ready to start.
