waveshare Single Board Computers Editorial Review
This Serial Expansion HAT for Raspberry Pi has received mixed reviews from customers. Some have praised its effectiveness in enabling multiple UART devices on a single Pi, stating that it works as advertised, while others have criticized the lack of documentation and support and reported issues with receiving data from the device. The product is stackable to 16 modules, offering up to 32-ch UART, has an onboard SC16IS752 2 Channels (2-ch) UART, 8 GPIOs, and I2C interface. One customer recommends using a larger resistor and adding dip switches to enable address and interrupt selection and suggests the seller provides better documentation on how to use the onboard GPIO. Another customer reported issues with both UARTs locking up, but after updating to the latest version of the Raspberry Pi OS, the device began to function correctly.
