7x10 R click carries a matrix of 70 red LEDs driven by a pairs of 8-bit serial-in, parallel-out shift registers, a Darlington Transistor array and a Johnson counter. 7x5 is a standard resolution for displaying ASCII characters, so 7x10 click is essentially a dual-character display capable of showing letters in more readable typefaces compared to a 14-segment display. The click communicates with the target MCU through the mikroBUS SPI interface (SCK, SDO, SDI), with additional functionality provided by R CLK, MR#, LATCH and R RST pins. 7x10 R click is designed to use either a 3.3V or a 5V power supply. |
