A 24-channel input/output port expander module controlled via I2C interface. It is based on the CH423 chip. Each IO pin can be configured as an input or output, including 8 with a hardware interrupt function. The maximum output current should not exceed 15 mA, and the pins are compatible with 3.3 V and 5 V. The expander will prove useful for LED lighting or matrix display projects. Full documentation is available on the product wiki page.
Expansion board for Arduino, allows easy connection of XBee modules, has separate outputs for I2C, SPI and UART buses. The built-in 3.3V voltage stabilizer and operating mode switch make it easier to program the Arduino when the XBee module is connected to the sockets. DFRobot DFR0265
