DESCRIPTION
4-SERIAL Ports RS485 and RS232 for Raspberry Pi
The latest versions of the Raspberry Pi have up to four UART ports on the GPIO connector, but you cannot use them without a physical layer transceiver.
This HAT is the perfect solution for connecting your Raspberry Pi to serial devices like sensors and industrial equipment. It supports RS485 and RS422 communication protocols, making it versatile for a wide range of applications. It implements either three RS232 plus one RS485, or two RS232 plus two RS485.
SPECIFICATIONS
One or two RS485 Ports: Max 921,600 bps
Two or three RS232 Ports: Max 230,400 bps
COMPATIBILITY
The card is compatible with Raspberry Pi versions from 2 to 5. Older versions of the Raspberry Pi might not have all the four serial ports available on the GPIO connector.
POWER REQUIREMENTS
The card takes 5V and less than 40mA of power from the Raspberry Pi GPIO connector.
STACKING MULTIPLE CARDS
Since the 4-Serial Ports Card uses the Raspberry Pi UART ports, only one card can be installed on each Raspberry Pi. However, the card is equipped with an extra tall 2x20 male-female connector, and can be installed on top of any stackable HAT. Also, any Raspberry Pi HAT can be installed on top of the 4-Serial Ports Card
