• Dimensions: 1.5 in x 2.05 in

The I2C-7SEG board is a 5-pin CMOS
device that provides 4-digit of 7-segment
display using I
external components required. Only two
signal lines SDA and SCL plus supply
voltage and ground are required to be
connected. This makes it perfect for
embedded systems that require LED
display.
This board features innovations that set it
apart from other 7-segment module.
Innovations feature like on-board I
address jumpers, pull-up resistors and
power LED. The module can be quickly
connected directly on to the breadboard.
The board is small and compact in size
1.50 x 2.05 inches.
The I2C-7SEG is designed base on
SAA1064 IC. The circuit is especially
designed to drive four 7-segment LED
displays with decimal point by means of
multiplexing between two pairs of digits. It
features an I
interface with the possibility to program
four different SLAVE ADDRESSES, a
POWER RESET flag, 16 current sink
OUTPUTS, controllable by software up to
21 mA, two multiplex drive outputs for
common anode segments, an on-chip
multiplex oscillator, control bits to select
static, dynamic and blank mode, and one
bit for segment test.
A jumper pins vary the fixed I
and allow up to four devices to share the
same I
