Serial port expansion chip: SC16IS752 Working voltage: 3.3V/5V RS485 transceiver: SP3485 Product size: 65 X 56.5mm Communication interface: SPI Through hole diameter: 3.0mm Communication speed: 300~921600 bps

Breakout SPI control pins, for connecting with host control boards like Arduino,comes with development resources and manual (examples in C and Python). 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. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic. Adopts SC16IS752+SP3485 dual chip combination, converts SPI to RS485, data rate up to 921600bps.Allows transceiving data manually or automatically, configured by DIP switch. Tandard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards.
