- Item #: 9SIVTU0M173360
- Mfr. Part #: HYH-20260709-C7CC-1999
- This is a 2-channel isolated RS485 expansion HAT designed for Raspberry Pi, 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.; UART expansion chip: SC16IS752. RS485 transceiver: SP3485. Communication interface: SPI. Data rate: 300 ~ 921600 bps. Operating voltage: 3.3V / 5V.; Allows transceiving data manually or automatically, configured by DIP switch.Onboard LEDs for indicating the power and transceiver status; Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic. Onboard auto-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance.
