Description
- This 2-CH RS485 HAT comes with 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 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, compatble Arduino boards .Comes with development resources and manual (examples in C and Python)
2-Channel Isolated RS485 Expansion HAT for Raspberry Pi, SC16IS752+SP3485 Solution, with Multi Onboard Protection Circuits
Overview
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, ADI 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.
