Description

This 8 digit seven segment display module uses a TM6138 controller allowing full control of the display using just 3 digital pins on a micro-controller. In addition to the seven segment display there are 8 individually controllable 3mm LEDs and a keypad with 8 push buttons arranged in a single row. These can also be controlled through the TM6138 IC and so require no extra digital pins. A standard 5 pin header provides easy interface to the module from microcontroller.
