Each 2×2 mm LED is driven by the ISSI IS31FL3741 controller chip over I2C, providing 8-bit PWM per colour channel for full 24-bit colour across the entire display.\n\nUnlike NeoPixel or DotStar LEDs, this matrix uses a single controller chip for all LEDs, with an adjustable global current driver for brightness control without losing colour resolution. The board supports 3.3V to 5V power and logic (5V recommended for best green and blue LED performance), and up to four boards can share one I2C bus for tiled displays.\n\nKey Features\n\n\n117 RGB LEDs (13×9 Grid) – 2×2 mm LEDs with 3 mm pitch spacing\n\nIS31FL3741 Controller – I2C-driven with 8-bit PWM per channel (24-bit colour)\n\nAdjustable Global Current – Brighten or dim the entire display without losing colour resolution\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection with daisy-chain support\n\n3.3V & 5V Compatible – Works with a wide range of microcontrollers (5V recommended)\n\nTileable Design – Place boards side-by-side; address jumpers support up to 4 on one I2C bus\n\nFour Mounting Holes – Easy to secure in enclosures and projects\n\n\nIdeal For\n\nCompact RGB LED displays and status indicators\nSimple animations and colour patterns\nWearable and portable LED projects\nI2C-based projects where simple wiring is preferred over HUB75\n\n\nPackage Contents\n\n1× Adafruit IS31FL3741 13×9 RGB LED Matrix (assembled)\n\n\n\nTip: I2C makes wiring simple, but pixel updates are slower than HUB75-style matrices. This display is ideal for small animations and status indicators — for video or large graphics, consider an HUB75 RGB matrix instead.\n\n\nResources\n\nAdafruit IS31FL3741 Guide\nArduino IS31FL3741 Library (GitHub)\nCircuitPython IS31FL3741 Library (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2928,"title":"Default Title","sku":"AF-5201","price":30.45,"on_sale":false,"in_stock":true,"available_quantity":40,"option1":"Default Title"}]}
