This dual-channel RS485 expansion HAT designed for the Raspberry Pi adopts an isolated transceiver to achieve isolation for RS485, which increases the reliability and anti-interference of data transmission in each channel. And it features embedded protection circuits such as a lightning and surge protector, a TVS diode, and power supply isolation to protect the Raspberry Pi development board effectively.

Besides, the order includes a screw accessory kit that allows users to tightly fix this board onto a Raspberry Pi controller.
