Equipped with an internal 8x8 static RAM, BCD decoder, and scan-limit register, the MAX7219 lets you update individual pixels without rewriting the entire screen. It supports both analog and digital brightness control as well as a 150µA low-power shutdown mode for energy-conscious builds.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 id=\"easy-cascading-and-ready-to-wire-hardware\" class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eEasy Cascading and Ready-to-Wire Hardware\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eThis green PCB module features a 5-pin input header on the left and a matching 5-pin output header on the right for effortless cascading.
