Description

This module uses chip TCA9555 or PCA9555A to realize I2C to GPIO conversion

The operating voltage of the TCA9555 or PCA9555A is 1.65V ~ 5.5V, while the PCA9555 (without A suffix) is 2.3V ~ 5.5V.

The TCA9555 is compatible with the PCA9555A and can be replaced directly.

TCA9555 TSOP-24 package chip screen identification PW555,

Module dimensions: 33.5mm x 23.5mm.

J1-J2 single row pin spacing: 800mil (2.54mm×8=20.32mm). Suitable for connecting to the breadboard.

All 16 IO ports have LED indicators.

LED is common anode design, using 2k resistance current limiting; When the IO port output is logical 0, the LED lights up.
