Designed to meet the needs of modern developers, the Pulse Click Board™ features the NE555 timer/pulse generator by Texas Instruments. This pulse generator comes with adjustable frequency configured in two steps. The circular central switch integrated in the middle of the board is used to first choose between four frequency bands with the aid of a frequency selector. Once the appropriate position is selected, the required output frequency is fine-tuned using the on-board potentiometer in a range between 0.05 Hz and 1000 Hz. The high-precision NE555 timer is designed to produce highly accurate time delays or oscillation. The resulting output can be configured to be sent either as a digital signal through the OUT pin or an interrupt (INT pin). The PULSE Click Board™ is designed to operate using either a 3.3V or 5V power supply only. With precise frequency control, it produces pulse generation for equipment testing and similar purposes.

With such features, this Click Board™ makes an ideal option for applications like fingerprint biometrics, iris biometrics, RFID reader, and so on.

  • Mode of operation: Mono-stable and a-stable mode
  • Timing from microseconds to hours
  • Supported by all MikroElektronika compilers
  • Uses a 3.3V or 5V power supply
  • Precise control
  • Adjustable duty cycle
  • Selectable output

Product Details

IC/Module: NE555 Precision Timer

The TI's NE555 timer is used as a pulse generator coupled with a circular switch and two potentiometers to adjust the frequency in a specified range. This precision timing IC produces highly accurate time delays. In mono-stable or time-delay mode, the timed interval is controlled by a single external resistor and capacitor network, while the frequency and duty cycle can be adjusted individually using two external resistors and a single external capacitor in the a-stable mode of operation.


Frequency Bands

The PULSE Click Board™ has an on-board circular switch that allows the user to select between four frequency bands. It starts from the six-o-clock position and moves counter-clockwise in quarters to select the appropriate position. The 4 frequency band options include: 0) Up to 100 Hz; 1) Up to 1 kHz; 2) Up to 10 kHz; and 3) Up to 100 kHz.

Note: An on-board zero-ohm SMD jumper enables the user to choose between a 3.3V and a 5V power supply source.
