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 PULSE click 2 3 4. Essential features The frequency of PULSE click is configured in two steps. First select between four frequency bands by using the frequency selector - a circular central switch in the middle of the board. Starting from the six-o- clock position and moving counter-clockwise in quarters, it has 4 options: 0) Up to 100 Hz 1) Up to 1 kHz 2) Up to 10 kHz and 3) Up Turn the board upside down so that Turn the board upward again. Make sure to 100 kHz. After you select the appropriate the bottom side is facing you upwards. to align the headers so that they are position, use the onboard potentiometer to Place shorter pins of the header into the perpendicular to the board, then solder the fine-tune the desired output frequency. appropriate soldering pads. pins carefully. 1. Introduction PULSE click is a pulse generator with an 3. Plugging the board in adjustable frequency. It carries the NEN555 precision timer capable of producing highly click Once you have soldered the headers your accurate time delays, and the output can board is ready to be placed into the desired be sent to the MCU through the OUT pin, BOARDS mikroBUS socket. Make sure to align the cut (default mikroBUS AN pin) or an interrupt www.mikroe.com in the lower-right part of the board with the (INT pin) or an interrupt (INT pin). An extra markings on the silkscreen at the mikroBUS output pin above the mikroBUS socket is socket. If all the pins are aligned also available.
