RS232 Hat Expansion PCB Board for Rapsberry Pi 4/3/2/A+/B+,Compact GPIO TX/RX/GND to DB9M RS232 Serial Expansion Board

Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards. Standard RS232 serial port , ideal to connect serial communication RS232 peripherals, industrial equipment (such as PLCs), serial console ports and special purpose equipment.
HAT compliant (No EEPROM), Male DB9 Socket (RS232/ RS-232), TX/RX/GND Solder Points. Expansion board size: 65mm*56.5mm, the standard Raspberry Pi HAT extension plate size.
Using ST3232 IC scheme, The Serial HAT features a Male DB9 RS232 port connected to the Pi's UART pins via a ST3232 IC. The ST3232 IC converts the Pi's UART port to RS232, which enables serial communication with any RS232 compatible serial device.The communication minimum guaranteed data rate is above 250 kbps .Support RS232. RS232: full-duplex communication.
ESD protection for RS-232 I/O pins,±15 kV human body model，±8 kV IEC 1000-4-2 contact discharge,300 μA supply current，6 V/μs minimum guaranteed slew rate.Meet EIA/TIA-232 specifications down to 3 V.
Package Included: Pi-232 HAT x1, Screws packx1, Screwdriver x1.
