Waveshare 2-Channel Isolated RS485 Expansion HAT, SC16IS752+SP3485 Dual Chip, SPI to RS485, Up to 921600bps, Raspberry Pi 4B/3B+/3B/2B/Zero/Zero W HAT
- Item #: 9SIVTM6M5A5668
- Mfr. Part #: 26-8CXY24-139
- 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.
