The MAX7219 8×8 LED Dot Matrix Display Module is a single-panel 8×8 red LED matrix driven by the MAX7219 driver IC, with a specified input voltage range of 3.7V to 5.3V that makes it the only MAX7219 dot matrix module in the StemVolt range confirmed compatible with 3.7V single-cell LiPo battery power — where standard 5V-typical modules may not initialize reliably from a direct LiPo cell output. The max7219 display module’s wider voltage acceptance means builders running battery-powered portable Arduino or ESP32 projects from a single 1S LiPo cell (3.7V nominal) can drive the dot matrix display directly from the LiPo output without a 5V booster circuit, simplifying power supply design in compact portable builds.
The max7219 led dot matrix module’s 50×32mm PCB houses the MAX7219 driver IC, the 32×32×6mm LED display panel at the front, and the SPI connection header at the rear, drawing 320mA at full brightness when all 64 LEDs are active simultaneously — this specified current figure allows the builder to calculate accurate LiPo battery runtime for portable builds where the max7219 module runs alongside other components on the same supply rail. The max7219 led matrix module connects via SPI using DIN, CS, and CLK plus power, and works with the MD_MAX72XX and LedControl libraries in Arduino IDE for pixel-level, row-level, and character display. The max7219 module can be cascaded by connecting DOUT to DIN of the next module in the chain.
Available from StemVolt. This max7219 module arduino display is ideal for Arduino ESP32 LiPo battery portable matrix icon animation and STEM project LED dot matrix display builds in India.
