Isolated RS485 RS232 HAT for Pi
Features At A Glance
Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
Adopts the combination scheme of SC16IS752, SP3485 and SP3232, converts SPI to one RS485 and one RS232
Onboard resettable fuse and protection diodes, ensure the stable output of RS485 current and voltage, prevent over-current and over-voltage, improve shock resistance
Onboard TVS (Transient Voltage Suppressor), can effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
Breakout SPI control pins, for connecting with Arduino and other host control boards
Onboard TVS (Transient Voltage Suppressor) And Resettable Fuse, Can Effectively Suppress Surge Voltage And Transient Spike Voltage In The Circuit, Improve Shock Resistance
