Atomic RS485 Base

SKU:A131

Description

Atomic RS485 Base is a TTL-RS485 converter based on the Atomic design, used for converting TTL level to RS485 level. RS485 is a widely used electrical standard in the industrial field, featuring stronger anti-interference capability and longer transmission distance. It has a built-in DC-DC step-down regulator chip, which can directly convert the 12V voltage of RS485 to 5V to power the ATOM, eliminating the trouble of separate power supply. When multiple devices require communication control, using the Atomic RS485 for interface type conversion will be a good choice.
