IS31FL373 Charlieplexed PWM LED Matrix Driver

Adafruit IS31FL373 Charlieplexed PWM LED Matrix Driver provides a classic LED look with the ability to PWM each individual LED in a 16x9 grid. This feature allows for beautiful LED lighting effects, without a lot of pin twiddling. Using the chip is as easy as programming which LED on the grid you want lit, and the brightness. The flexible IS31FL3731 uses 2.7-5.5V power and logic for use with any microcontroller. The address can be set so up to 4 matrices can share an I²C bus. Inside is enough RAM for 8 separate frames of display memory to set up multiple frames of an animation and flip them to be displayed with a single command.

31FL323x LED Lighting Development Boards

ISSI 31FL323x LED Lighting Development Boards are development tools that evaluate ISSI multi-channel LED drivers. LED drivers are electrical circuits used to power light-emitting diodes. The fully assembled and tested board is powered by the Arm® Cortex®-M3 or 80C51 (IS31FL3235A-QFLS2-EB) with a 5V operating supply voltage. The evaluation boards have multiple display modes.

IS31LT3360 Demonstration Board

ISSI IS31LT3360 Demonstration Board is a fully assembled and tested PCB that uses the IS31LT3360 continuous mode inductive step-down converter. This ISSI board is designed to drive single or multiple series connected LEDs. This performance is achieved efficiently from a voltage source higher than the LED voltage.
