Arduino i2c pwm expander. This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2. Apr 11, 2018 · Need A Thousand Extra PWM Pins? If your Arduino runs out of I/O lines, you can always add one of the several I/O expander chips that takes a serial interface to set its several pins. This tutorial will serve to familiarize you with all things SX1509 and the SparkFun Breakout. The PCF8575 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I2C interface [serial clock (SCL), serial data (SDA)]. My plan is to run several Mosfets with different Loads and control them with this PWM Expander. The PCF8575 is a 16-bit I/O extender controlled by the I2C bus. Or It's a really cool chip and a great tool for expanding the capability of your Arduino or any other I 2 C-capable microcontroller. 5-V to 5. 5-V VCC operation. . This device allows us to have 16 additional GPIO using only two pins of a processor like Arduino.
