Serial console on Raspberry Pi

Here is my approach to get a serial console on the Raspberry Pi: use a FTDI USB TTL-232R-3v3 cable with a 6-pin header!

The cable (e.g. from here, many alternatives available) translates the 3.3 Volt signals of the Raspberry's header (GND, RXD, TXD) to a USB serial interface. Just remember to cross-connect TX on the Raspberry header with RX on the FTDI cable's header.


I had the FTDI cable lying around, here are cheaper options!

Voltcraft DSO-3062C oscilloscope

'Upgraded' to 200 MHz and controlled from Linux via dso-usb-tool. I'm happy with the 300 EUR device :-)

Did I mention it runs Linux (on a Samsung ARM9 SoC, S3C2440)?

Screenshot shows the beginning of the devices probing on some 400KHz I2C bus.
