×

描述

The AS1115 is a compact, I²C interfaced, dot-matrix LED driver for a 8x8 LED matrix or 8x 7-segment LEDs. It includes a 4-bit PWM for each segment and an external resistor can be used for analog current adjustment up to 5mA per LED. In addition the AS1115 can read back 16 keys and offers a detailed short/open LED error diagnostic.
