14-Segment LED DISPLAY MAX7219

Project of 14-segment, four signs LED displays controlled by Maxim's MAX7219 chips. Unusual distribution of leads and connections of LED displays (ELD-527RDB have only 13 pins for four 14-segment characters). The pcb design provides for a chain connection of displays as it contains connectors on the left and right side. Exquisite PCB workmanship, high precision. Made in accordance with the design. Very fast delivery. PCB's arrived a month ahead of schedule.
