DESCRIPTION

8-SERIAL Ports 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. 
Raspberry Pi Serial Ports
The Eight Serial Ports HAT uses all the four ports of the Raspberry Pi, plus eight aditional ports from two 32 bit ARM Cortex processors, to implement all the common serial ports in use today. The processors talk to the Raspberry Pi using only the I2C port, with the hardware address selectable from a DIP switch. One LED for each port shows when the port is active.

SPECIFICATIONS

RS485 Ports: Max 921,600 bps
RS232 Ports: Max 230,400 bps
RS422 Ports: TBD
1-Wire: TBD
CAN: TBD
M-BUS: TBD

COMPATIBILITY

The card is compatible with Raspberry Pi versions from 3 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 100mA of power from an external 5V power supply. It provides also up to 3.5A of power through the hardware watchdog to the Raspberry Pi

STACKING MULTIPLE CARDS

Two 4-Serial Ports Cards can be stacked on top on one Raspberry Pi, implementing a total of 16 serial ports.

CARD LAYOUT
MECHANICAL SPECIFICATIONS
The 4-Serial Port Card has the same mechanical specifications with all the Sequent Microsystems cards in the Industrial Automation family.
