[ART-Pi] Communication master station based on POWERBUS

[ART-Pi] Communication master station based on POWERBUS 1. Introduction to POWERBUS Powerbus is a power supply bus chip independently designed and invented in China. It is a low-voltage DC carrier power supply bus chip. It is a kind of RS-485 four-wire system (two-wire system). (one power supply line and two communication lines), and the power supply line and the signal line are combined into one, realizing the technology of sharing a bus for signal and power supply. Due to its performance of non-polar wiring and arbitrary topology, it avoids problems that occur during construction. Wiring errors thus simplifying construction design easily. 2. Expansion board function 1. DC 24V power input. The communication master station provides power to the second bus load through the second bus interface. On the other hand, it realizes communication between the master station and the slave station load through the second bus. The baud rate of the second bus communication is 2400bps and 9600bps optional. 2.
