(2-Channel Isolated RS485 Expansion HAT for Raspberry Pi)
개요
본 제품은 라즈베리용 절연된 2채널 RS485 확장 HAT입니다.
SC16IS752 및 SP3485 칩을 탑재하여 SPI를 RS485로 변환하여 줍니다.
라즈베리의 SPI를 이용하여 2채널 RS485 통신을 할 수 있으며, 절연되어 있어 보드를 예기치 않은 상황으로부터 보호할 수 있습니다.
특징
Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
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
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
Onboard LEDs for indicating the power and transceiver status
Breakout SPI control pins, for connecting with host control boards like Arduino
Comes with development resources and manual (examples in C and Python)
