This is the 8" LED Scoreboard. This fun and very practical. It is already assembled and consists of a 2-digit, microprocessor-controlled UP/DOWN counter with RESET.

It has three separate screw-terminal inputs, RESET, UP, & DOWN, which are looking for a switch to ground. The power comes in on a 2-pin screw terminal and can be anywhere from 9vdc to 15vdc. It will run off of a 9v Battery.

There are 50 jumbo 10mm LEDs and each number is 4 1/2 inches high by 2 3/4 inches wide. The total width of the two numbers, including the spacing between them is 4 inches. The visibility is well over 100 feet.

Leds can be mounted on either side of the PCB. The Front end style is where the LEDS are mounted so that the other components can be seen. shown pictures above with the RED scoreboard Leds. The Pictures of the Green scoreboard is a backside style led mount. The counter will start at zero upon initial power. For better readability, the Tens digit is always off when the Ones digit is from zero to 9. We have 4 different colors. Message us the color you want a different color. The default color is RED. The software has built-in debounce protection to avoid double entries. The counter will count up all the way to 99, then rollover to 0 and continue to count from there. The counter can count down from 99 to 0 and thru 0 back to 99. The RESET will bring you to 0 from any count.

It uses a Microchip PIC16F57 as the processor and it comes in an IC socket which means you can take it out and re-program it to your needs. This device can be driven by an Arduino.

The PCB is 8 inches wide by 6 1/2 inches high. FR-4 epoxy-glass, .062", double-sided, plated-thru holes. There are also five mounting holes.
