The Serial Expansion HAT is a peripheral designed to enhance the communication capabilities of various Raspberry Pi models. It provides additional UART channels and GPIO pins through an I2C interface, making it ideal for projects requiring more serial communication options or general-purpose input/output. This HAT is particularly useful for developers and hobbyists working on embedded systems or IoT projects that need extended connectivity without consuming the Pi's native pins.
The HAT features two UART channels and eight programmable GPIOs, all accessible via the I2C interface. This allows users to connect multiple serial devices or sensors without needing to use the Raspberry Pi's primary UART or GPIO pins. The onboard SC16IS752 chip handles the expansion, ensuring reliable communication and reducing the need for additional hardware.
The design of the HAT is compact and stackable, allowing up to 16 modules to be connected simultaneously by adjusting the address jumpers. This makes it possible to manage up to 32 UART channels in a single setup. The inclusion of status LEDs helps users monitor the UART activity, providing visual feedback on the communication status.
The HAT includes reserved I2C control pins, which allow it to work seamlessly with other control boards or peripherals that use the I2C protocol. This compatibility ensures that users can integrate this HAT into more complex systems without worrying about signal conflicts or wiring issues. The setup process is straightforward, requiring only basic soldering for the address jumpers if needed.
