Χαρακτηριστικά

Isolated RS485 RS232 Expansion HAT For Raspberry Pi, SPI Control, Onboard Protection Circuits

Isolated RS485 RS232 HAT For Pi

Comes with development resources and manual

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
Comes with development resources and manual (examples in C and Python)

Standard Raspberry Pi 40PIN GPIO Header

Suitable For Raspberry Pi Series Boards

RS485 And RS232 Support

RS232: Full-Duplex Communication, SP3232 Transceiver
