DESCRIPTION:
2-Channel Isolated RS485 HAT For Raspberry Pi, SPI communication. Bulit-In Power Supply Isolation, Magnetical Isolation, And TVS Diode, Etc.
Features:
This is a 2-channel isolated RS485 expansion HAT designed for Raspberry Pi, adopts the SC16IS752+SP3485 solution, with embedded protection circuits such as power supply isolation, magnetical isolation, and TVS diode, etc. It is easy to control the 2-channel RS485 for auto-transceiving via SPI interface. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for fields like industrial automation.
- 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, lightningproof & anti-electrostatic
- Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, and improves shock proof performance
- Onboard LEDs for indicating the power and transceiver status
- Breakout SPI control pins, for connecting with host control boards like Arduino
- Comes with online development resources and manual (examples in C and Python)
