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. 8x8 B click 2 1 3 1. Introduction 4. Essential features Turn the board upside down so that bottom side is facing you upwards. Place shorter parts of the header pins in both soldering pad locations. 8x8 B Click™ is an accessory board in mikroBUS™ form factor. It’s a compact and easy solution for adding 8x8 BLUE LED matrix to your design. It features MAX7219 8-digit LED display driver module as well as 64 BLUE LED diodes. 8x8 B Click™ communicates with target board microcontroller via four mikroBUS™ SPI lines (DIN, DOUT, CLK and CS). The board is designed to use 5V power supply only, but it can be used with 3.3V MCUs as well. Turn the board upward again. Make sure to align the headers so that they are perpendicular to the board, then solder the pins carefully. 3. Plugging the board in Once you have soldered the headers your board is ready to be placed into desired mikroBUS™ socket. Make sure to align the cut in the lower-right part of the board with the markings on the silkscreen at the mikroBUS™ socket. If all of the pins are aligned correctly, push the board all the way into the socket. 8x8 B Click™ with it’s MAX7219 IC gives additional 8x8 BLUE LED matrix to your design. The MAX7219 is serial input/ output common-cathode display driver with SPI interface. It has BCD code-B decoder, analog and digital brightness control, 8x8 static RAM and several useful registers. click BOARD www.mikroe.com 8x8 B click Manual ver. 1.00 0 100000 022146 6.
