This board adopts SC16IS752+SP3485 dual chip combination, converts SPI to RS485, data rate up to 921600bps, with embedded protection circuits such as power supply isolation, ADI magnetical isolation, and TVS diode, etc.
With Standard Pi 40PIN GPIO extension header, supports Raspberry Pi series boards. Breakout SPI control pins, for being compatible with host control boards.
It allows transceiving data manually or automatically, configured by DIP switch. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, llghtningproof & anti-electrostatic.
Onboard auto-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance. Onboard LEDs for indicating the power and transceiver status.
Due to its fast communication, stability, reliability, and safety, it's an ideal choice for fields like industrial automation. Provide online development resources and manual (examples in C and Python).
