7x10 G click
7x10 G click

Description of product


7x10 G click can be used for displaying letters on a display with 7x5 font resolution. It carries a matrix of 70 green LEDs driven by a pair of 8-bit serial-in, parallel-out shift registers, a Darlington Transistor array and a Johnson counter.

7x10 G click is designed to run on either 3.3V or 5V power supply.It communicates with the target microcontroller over SPI interface, with additional functionality provided by the following pins on the mikroBUS™ line: AN, PWM, RST.

How it works

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 dot matrix can also show scrolling text, thus fitting longer messages in small space. The pair of 8-bit SIPO shift registers drive the display. The current amplification necessary for driving the LEDs is performed by a Darlington Transistor array while a Johnson counter performs the necessary LED multiplex.
