7 Segment LED Module CB-035
Overview
The CB-035 device is an, 8-digit 7-segment display.
Each segment can be individually addressed and updated separately using a 2 wire I²C
interface. Only one external resistor (RSET) is required to set the current. LED brightness
can be controlled by analog or digital means.
The device include an integrated BCD code-B/HEX decoder, multiplex scan circuitry,
segment and display drivers, and a 64-bit memory. Internal memory stores the shift
register settings, eliminating the need for continuous device reprogramming.

Configuration
• The I²Cserial method requires only two pins for communication– SDA (serial
data) and SCL (serial clock).
• The default slave address is factory-set to 0000000.
•The Last bit of the address byte (R/W) define the operation to be
performed. When set to a 1 a read operation is selected, when set
to a 0 a write operation is selected.
