Raspberry PI Console Card - Features

  • Console port lets you talk to your Raspberry Pi over USB without a keyboard/mouse/monitor or Ethernet connection.
    • 115200 baud
    • Real FTDI chip (FT230XS)
  • Raspberry Pins
    • Pin 8 is TxD (out from Pi)
    • Pin 10 us RxD (in to Pi)
  • USB Mini-B connector
    • Mounted on the bottom of the card (See also our Micro USB version)
  • Jumper selectable - power the Pi from your computer's USB port
    • Newer Pi cards may take too much power
  • Transmit/receive LEDs
  • (3) Pi Connector options - extender allows daughtercards to be added on top
    • 26-pin extender connector works with Model A and Model B Pis
    • 40-pin extender connector works with Model A+, Model B+ Pis and the new Pi 2
    • 26-pin non-extender connector works with all Model Pis

Driver

  • Finding your COM port can be a hassle in Windows. Here's how we find the port in Window 8.1
    • Run Device Manager
    • Expand the Ports (COM & LPT)
    • USB Serial Port is the RPI-Console card (COM5 in this instance, your mileage may vary)

Troubleshooting

Raspberry Pi 3 problem described below (with solution):

With the release of the Raspberry Pi 3 the original hardware UART from the Broadcom processor 
has been reassigned to the Bluetooth chipset and the UART output on the GPIO pins now uses a mini-uart port. 
The mini-uart doesn't have a separate clock divisor and uses the core clock frequency.
