IO Expander

Applications

This module is primarily designed for engineers with a certain level of electronic knowledge. The module is equipped with 8 I/O channels, of which 4 are digital input/output and 4 are analog input/output. It also provides multiple power interfaces, making it easy to drive other devices and read different types of sensors.
If the operating voltage of the peripheral devices is 5V or 3.3V, they can be powered directly by the host, but please note that the current limit is 200mA. Additionally, you can use an external power supply to power both the module and your devices. While providing power, the external power supply will also charge the host.
