Add an IEEE1284 compatible parallel port and 9 pin D-sub RS232 serial port to your Raspberry Pi. Comes with printed installation guide including circuit diagram, fixings, and plastic standoffs to securely attach the HAT to any Raspberry Pi with a 40 pin expansion header. Perfect for
- Experimenter projects requiring easy access to 5V logic signals
- Driving CNC routers
- Use with parallel port printers
The serial port includes a line driver for TXD/RXD and RTS/CTS hardware handshaking.
On RISC OS the parallel port requires a soft loadable driver module (see resources).
The serial port driver is built into the OS.
On Linux a loadable kernel module parport_sphat is available (see resources) which presents a standard parport interface and entry as /dev/lp0. Supports Raspberry Pi 5 and earlier models with a 40 pin expansion header. Remember that the Raspberry Pi is not an x86 PC though, so there are no registers at 0x378 to peek and poke!
The serial port driver is built into the OS.
