Kimat TV Module

The Layad Circuits’ Kimat TV module allows the user to drive any television/monitor with A/V (via RCA jacks) inputs using an Arduino board as a host device for displaying monochrome text. The module also has builtin push buttons that can be used as inputs. The internal graphics controller handles all complexities associated with the implementation of using televisions or monitors with microcontrollers. While this may be done by software alone, such will entail extensive use of processor, memory and peripheral resources and is typically very challenging to implement with other user algorithms. With the Kimat TV module, no complicated programming or handling of several interrupts is required. This results in very minimum load on the host microcontroller (Arduino) and therefore allowing the user program to implement useful programs with ease. Similar to the use of common alphanumeric LCD’s, the Arduino host simply needs to feed the data that needs to be displayed to the module via the library provided.

applications:
 Queuing Systems
 HMI
 Ticketing
 Point of Sales
 Kiosks
 Score Boards
 Datetime Display
and Alarm

POWER REQUIREMENTS
The module may be powered with a regulated 5-volt source via the 5V pin header. This allows it to be conveniently powered from the 5V output pin of the Saleng Uno or any Arduino board. The module may also be powered from an external DC power supply rated with at least 50 mA and a voltage of 6 to 9V.

JUMPER OPTIONS
The 3-pin header with the label “NTSC” and “PAL” allows the user to choose whether the output format of the Kimat TV module is NTSC or PAL. Set the jumper accordingly. After setting the jumper, power cycle the Kimat TV module or press its reset button for the new output format to take effect.
