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 ROTARY R click 2 3 4. Essential features 1. Introduction Rotary R click with its LED ring is a perfect solution for implementing an input knob into your design (in contrast to a potentiometer, a rotary encoder can be spun round continuously). A single rotation is divided into 15 discrete steps. The encoder outputs A and Turn the board upside down so that Turn the board upward again. Make sure B signals (out of phase to each other). The the bottom side is facing you upwards. to align the headers so that they are knob is also a push-button outputted through Place shorter pins of the header into the perpendicular to the board, then solder the the interrupt line. The LED ring are controlled appropriate soldering pads. pins carefully. through the SPI interface. Rotary R click carries a 15-pulse incremen- 3. Plugging the board in tal rotary encoder with detents, surrounded click by a ring of 16 red LEDs. It communicates Once you have soldered the headers your with the target board through mikroBUS board is ready to be placed into the desired BOARD SPI lines (CS, SCK, MISO, MOSI), and three mikroBUS socket. Make sure to align the cut www.mikroe.com additional lines for outputting the Encoder in the lower-right part of the board with the info: ENCB OUT, ENCA OUT and SW (in markings on the silkscreen at the mikroBUS ROTARY R click manual place of the standard AN, RST and INT pins, socket. If all the pins are aligned ver 1.00 respectively). Rotary R click can be used correctly, push the board all with either a 3.3V or 5V power supply. the way into the socket. 01000000773995.
