This saves dozens of valuable GPIO pins on your Arduino, ESP32, Raspberry Pi, or STM32 development boards. Each digit can be addressed individually, and the onboard display updates smoothly without flickering, thanks to an integrated BCD code-B decoder, multiplex scan circuitry, and internal segment drivers.<\/p>\n<p data-path-to-node=\"8\">A convenient, single external resistor sets the panel brightness, preventing uneven lighting across segments. Additionally, the module supports a low-power shutdown mode, making it an excellent choice for power-sensitive IoT projects, digital clocks, counters, panel meters, and custom electronic dashboards.<\/p>\n<ul>\n<li data-path-to-node=\"10,0,0\"><b data-path-to-node=\"10,0,0\" data-index-in-node=\"0\">Minimal Pin Count:<\/b> Controls 8 numeric digits using just 3 digital I\/O pins via an SPI-like serial interface.<\/li>\n<li data-path-to-node=\"10,1,0\"><b data-path-to-node=\"10,1,0\" data-index-in-node=\"0\">Cascade Support:<\/b> Includes input and output pin headers, allowing multiple modules to be daisy-chained together to create larger displays.<\/li>\n<li data-path-to-node=\"10,2,0\"><b data-path-to-node=\"10,2,0\" data-index-in-node=\"0\">Flicker-Free Operation:<\/b> Integrated 150\u00b5A low-power shutdown mode and hardware-driven multiplexing handle the display refresh entirely on-chip, freeing up your MCU\u2019s processing power.<\/li>\n<li data-path-to-node=\"10,3,0\"><b data-path-to-node=\"10,3,0\" data-index-in-node=\"0\">Flexible Formatting:<\/b> Easily display numbers, decimals, negative signs, and select alpha characters<\/li>\n<\/ul>\n<p><strong>Technical Specifications:<\/strong><\/p>\n<table data-path-to-node=\"13\">\n<thead>\n<tr>\n<td><strong>Parameter<\/strong><\/td>\n<td><strong>Specification<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"13,1,0,0\"><b data-path-to-node=\"13,1,0,0\" data-index-in-node=\"0\">Driver IC<\/b><\/span><\/td>\n<td><span data-path-to-node=\"13,1,1,0\">MAX7219 (Common Cathode)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"13,2,0,0\"><b data-path-to-node=\"13,2,0,0\" data-index-in-node=\"0\">Display Configuration<\/b><\/span><\/td>\n<td><span data-path-to-node=\"13,2,1,0\">8 Digits, Two 4-Digit 7-Segment Panels<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"13,3,0,0\"><b data-path-to-node=\"13,3,0,0\" data-index-in-node=\"0\">LED Color<\/b><\/span><\/td>\n<td><span data-path-to-node=\"13,3,1,0\">Red \/ Blue \/ Green <i data-path-to-node=\"13,3,1,0\" data-index-in-node=\"19\">(Specify choice on variant)<\/i><\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"13,4,0,0\"><b data-path-to-node=\"13,4,0,0\" data-index-in-node=\"0\">Operating Voltage<\/b><\/span><\/td>\n<td><span data-path-to-node=\"13,4,1,0\">4.7V to 5.3V DC (5V Typical)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"13,5,0,0\"><b data-path-to-node=\"13,5,0,0\" data-index-in-node=\"0\">Operating Current<\/b><\/span><\/td>\n<td><span data-path-to-node=\"13,5,1,0\">150 mA to 330 mA (Depending on active segments\/brightness)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"13,6,0,0\"><b data-path-to-node=\"13,6,0,0\" data-index-in-node=\"0\">Shutdown Current<\/b><\/span><\/td>\n<td><span data-path-to-node=\"13,6,1,0\">150 \u00b5A<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"13,7,0,0\"><b data-path-to-node=\"13,7,0,0\" data-index-in-node=\"0\">Communication Interface<\/b><\/span><\/td>\n<td><span data-path-to-node=\"13,7,1,0\">3-Wire Serial (SPI Compatible: DIN, CS, CLK)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"13,8,0,0\"><b data-path-to-node=\"13,8,0,0\" data-index-in-node=\"0\">Data Transfer Rate<\/b><\/span><\/td>\n<td><span data-path-to-node=\"13,8,1,0\">Up to 10 MHz<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"13,9,0,0\"><b data-path-to-node=\"13,9,0,0\" data-index-in-node=\"0\">Fixing Holes<\/b><\/span><\/td>\n<td><span data-path-to-node=\"13,9,1,0\">4x M3 Holes (Diameter: 3mm)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"13,10,0,0\"><b data-path-to-node=\"13,10,0,0\" data-index-in-node=\"0\">Dimensions (L x W x H)<\/b><\/span><\/td>\n<td><span data-path-to-node=\"13,10,1,0\">82 mm x 15 mm x 12 mm<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3 data-path-to-node=\"15\"><strong>Pinout Mapping:<br \/>\n<\/strong><\/h3>\n<p><strong>Input Side (Left &#8211;
