ModMyPi Serial HAT (RS232)

RS232 is a legacy serial communication standard used in millions of devices globally including: printers, modems, data terminals, interface devices (keyboards/joysticks/mice), medical equipment, servers, instrumentation, industrial control equipment (PLC's, CNC, embedded computers), microcontroller development kits, service access points, sensor interfaces and many more! Many are being superseded by USB or even Bluetooth Low Energy but RS232 is still used in a lot of places and on loads of legacy equipment!

You can connect to the RS232 port on the Serial HAT via the male DB9 port (through use of a serial/null-modem cable) or via the TX/RX/GND solder points on the Serial HAT PCB. The Serial HAT can also be used for remote terminal access to your Raspberry Pi using a computer. You'll need a Female to Female Null Modem Cable, and a Serial to USB cable to achieve this!

The included 40 Pin "Single Shroud" Header, and 14mm Mounting Kit are designed to work with the HighPi Raspberry Pi Case.

Features:

• Serial Interfact HAT for the Raspberry Pi B+/2/3 (Also works with Zero/ZeroW, but it is HAT size)
• HAT Compliant (No EEPROM)
• Male DB9 Socket (RS232 / RS-232) 
• MAX3232 IC
• TX/RX/GND Solder Points
• Uses SMT Socket Header & 40 Pin Extra Tall "Single Shroud" Header
• Includes 14mm Mounting Kit
