MIKROE-1898

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 PWM click 2 3 4. Essential features PWM click can be used to control anything from a LED strip, set of servo motors, to a complex robot with a multitude of moving parts. The board has an additional set of pins that allow you to connect up to seven Turn the board upside down so that Turn the board upward again. Make sure PWM clicks together (using three jumpers 2 the bottom side is facing you upwards. to align the headers so that they are to specify a different I C address for each Place shorter pins of the header into the perpendicular to the board, then solder the one). This way, you can get a total of 112 2 appropriate soldering pads. pins carefully. PWM outputs on a single I C line 1. Introduction 3. Plugging the board in click PWM click is a simple solution for con- Once you have soldered the headers your trolling 16 PWM outputs through a single board is ready to be placed into the desired 2 BOARD I C interface. The click board carries the mikroBUS socket. Make sure to align the www.mikroe.com PCA9685PW IC. In addition to mikroBUS cut in the lower-right part of the board with 2 I C pins (SCL, SDA), the board also uses a the markings on the silkscreen at the LOW Output Enable Input pin (OE), which is mikroBUS socket. If all the PWM click manual ver 1.01 in place of the default mikroBUS RST pin. pins are aligned correctly, PWM click is designed to use either a 3.3V or push the board all the way 5V power supply. into the socket. 01000000785638.
