DESCRIPTION

2-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.

SPECIFICATIONS

RS485 Port: Max 921,600 bps
RS232 Port: Max 230,400 bps

COMPATIBILITY

The card is compatible with Raspberry Pi versions from 2 to 5. UART1 (pins 8, 10) is available on all Raspberry Pi cards, so the RS485 port will always work. UART1 might not be available on older versions, or on other cards which emulate the Raspberry Pi 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 2-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 2-Serial Ports Card
