type: Raspberry Pi Hat
Vendor: Byte 2 Bot

Description:

This Raspberry Pi Hat was designed for those who need a flexible serial UART connection with another device.  The male DB9 connector provides a full RS232 hardware interface just like older PCs used to.

The jumpers allow various configurations without changing any other hardware.  

  • Loopback (TX and RX connected together, so what is sent is automatically received)
  • Null Modem (TX and RX swapped on the board. Useful for straight-through cables)
  • Straight Through (This is useful when you have a null-modem cable)
  • Handshaking
    • CTS and RTS can be configured as straight through, or they can be swapped.
    • Cable DCD, DTR,DSR, and RI can be connected in any configuration

The hat comes with 11mm M2.5 standoffs, screws, and nuts.  Serial cables are available separately.
