RS485 bus adapter + DC/DC supply from RS485 for Atom

Tail485 is a RS485 converter designed for ATOM, which is used for converting RS485 signals to TTL and can also power up you Atom from the RS485 bus.

RS485 is an industrial standard defining the electrical characteristics of the receivers or emitter. The RS485 is widely used in industrial environment to establish a multi-point serial communication network. RS485 allow long distance communication in noisy electrically condition.

The TailRS485 is a convenient choice when you need to communicates with equipement over the RS485, the tailRS485 will act as interface switching. This products includes a DC/DC voltage regulator chip to convert the RS485 bus voltage (12V) to 5V. This will allows to power-up an atom via its USB typeC interface from the RS485 bus (convenient to avoids deploiement of separate power supply for the Atom).

Please note that the module is designed to be powered from the RS485 (it will not power-up the bus).

Designed for Atom Lite and Atom (not included), this product will allow to create a multi-point communication project.
