The CANABLOX® 144 LED Matrix Display CX-LEDMX-MH is built around the IS31FL3731 LED driver IC, which provides autonomous PWM control (8-bit, 256 steps), 144 LEDs multiplexing, and onboard frame memory for smooth animations without constant MCU refresh. The brightness is individually adjustable per LED, and the chip supports multiple display frames. The CX-LEDMX-MH offers an easy way to create text, symbols, and visual effects in compact embedded projects. It comes in the “MH” form factor (2×1 Slot).
The picture shows clear LEDs, but the product comes with red colored LEDs since red tinted LEDs provide a much better readability and brightness when powered by only 3.3V.
Selectable I2C address: 0x74, 0x76, 0x77

Note:
Through-Hole (TH) connectors, like the I2C pin header or screw terminals, are included but not factory assembled.
The CANABLOX® ecosystem
CANABLOX® is a modular, clean, stackable ecosystem that replaces the chaos of traditional prototyping with I2C-connected building blocks.
CANABLOX® is not just a hobby tool; it’s a stepping stone from prototype to finished product. With over 60 modules envisioned, from environmental sensors to serial bridges and audio applications, CANABLOX® becomes a platform, not just a product.
Every CANABLOX® module connects directly to a sturdy baseplate or standardized cables, letting you build solid, real-world systems – without the clutter.
All modules use standardized CANABLOX® slot sizes and can be connected either through 4-pin JST-SH cables (compatible with Qwiic and Stemma QT) or by direct mounting onto the baseplate with headers. Every baseplate includes I2C headers (not assembled) and mounting hardware.
