Two Serial Ports RS485 and RS232 Stackable HAT for Raspberry Pi

FEATURES Two Serial Ports RS485 and RS232 Stackable HAT for Raspberry Pi RS485 transceiver connected to Raspberry Pi UART1 (GPIO pins 8, 10) RS232 transceiver connected to Raspberry Pi UART3 (GPIO pins 32, 33) Compatible with Raspberry Pi versions 3, 4, and 5 Stackable with any other HAT (only one card per Raspberry Pi) Compact size (93mm x 13mm) Pluggable Connectors 26-16 AWG wires Status LEDs on both serial ports No additional software required (drivers included in the Linux kernel) All mounting hardware included: stand-offs, screws and nuts ECCN Code EAR99 3D FILES TWO SERIAL PORTS HAT 3D STEP MODEL DOWNLOAD TWO SERIAL PORTS HAT WITH RASPBERRY PI STEP MODEL DOWNLOAD   DESCRIPTION Two 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 DATA RATES: RS485 Port: Max 921,600 bps RS232 Port: Max 230,400 bps PORT ALLOCATION: RS485  -> /dev.ttyAMA0 RS232 -> /dev/ttyAMA4 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 Two 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 CARD LAYOUT MECHANICAL SPECIFICATIONS The Two Serial Ports Card is probably the smallest HAT in the world, measuring only 93mm x 14.2mm.   DOWNLOADS Serial Ports Downloads SOFTWARE The 2-Serial Ports Card does not require software. All the software drivers are part of the Linux kernel. YOUR KIT When you purchase the 4-Serial Ports Card you will receive the following items: 1. 2 Serial Ports add-on HAT for Raspberry Pi 2. Mounting hardware Two M2.5x18mm male-female brass standoffs Two M2.5x5mm brass screws Two M2.5 brass nuts 4. Connector plugs
