{"title":"SparkFun Large Digit Driver","handle":"sparkfun-large-digit-driver","url":"/products/sparkfun-large-digit-driver","description":"The SparkFun Large Digit Driver is a chainable controller board that solders directly to the back of 6.5\" 7-segment LED displays. It uses the TPIC6C596 shift register IC to drive individual segments, making it easy to build multi-digit scoreboards, lap timers, and large-format numerical displays visible from a distance.\n\nThe board attaches via 10 castellated pads at the bottom and 2 at the top. It requires dual power: 12V for the LED segments and 5V for the driver IC. Six input and six output pins (GND, LAT, CLK, SER, 5V, 12V) enable daisy-chaining multiple drivers together for multi-digit displays.\n\nKey Features\n\n\nChainable Design – Daisy-chain multiple drivers for multi-digit displays\n\nDirect Mount – Solders to the back of 6.5\" 7-segment displays via castellated pads\n\nTPIC6C596 Driver – Shift register IC for serial segment control\n\nDual Power Input – 12V for LEDs, 5V for driver IC\n\n6-Pin I/O – GND, LAT, CLK, SER, 5V, 12V on both input and output\n\n\nSpecifications\n\n\nDriver IC – TPIC6C596\n\nIC Supply Voltage – 5V\n\nLED Supply Voltage – 12V\n\nInterface – Serial (Clock, Latch, Data)\n\nMounting – Castellated through-hole pads\n\n\nIdeal For\n\nScoreboards and sports timers\nLap counters and race displays\nLarge-format clocks and countdown timers\nAny project needing digits visible from a distance\n\n\nPackage Contents\n\n1× SparkFun Large Digit Driver Board\n\n\nResources\n\nLarge Digit Driver Hookup Guide\nHow to Solder Castellated Mounting Holes\nTPIC6C596 Datasheet (PDF)\nSchematic (PDF)\nEagle Design Files (ZIP)\nGitHub Repository\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11845,"title":"Default Title","sku":"SF-WIG-13279","price":19.61,"on_sale":false,"in_stock":true,"available_quantity":186,"option1":"Default Title"}]}
