Description
The LED Display Slaved is designed to show the flexibility provided by using
I2C to connect periferals to a project.
It uses an ATmega88/328 chip with a ULN2803 driver to drive 0.56" LED 7 segment
displays configure into two groups of 4.
Power is supplied through the I2C bus and is a max of 40ma with 5v.
There are jumper to control the use of the I2C terminators.
