A PCF8574 expander example in micropython using a Raspberry Pi Pico
by rp2040guy71In this example we connect a PCF8574 expander to a Raspberry Pi Pico Description This 8-bit input/output (I/O) expander for the two-line bidirectional bus (I2C) is designed for 2.5-V to 6-V VCC operation. The PCF8574 device provides general-purpose remote I/O expansion for most microcontroller families…
