### How do I change the serial baud rate?
The default baud rate is 250000 in both the Klipper micro-controller
configuration and in the Klipper host software. This works on almost
all micro-controllers and it is the recommended setting. (Most online
guides that refer to a baud rate of 115200 are outdated.)
The recommended baud rate for Klipper is 250000. This baud rate works
well on all micro-controller boards that Klipper supports. If you've
found an online guide recommending a different baud rate, then ignore
that part of the guide and continue with the default value of 250000.
If you need to change the baud rate, then the new rate will need to be
configured in the micro-controller (during **make menuconfig**) and
that updated code will need to be flashed to the micro-controller. The
Klipper printer.cfg file will also need to be updated to match that
baud rate (see the example.cfg file for details). For example:
If you want to change the baud rate anyway, then the new rate will
need to be configured in the micro-controller (during **make
menuconfig**) and that updated code will need to be compiled and
flashed to the micro-controller. The Klipper printer.cfg file will
also need to be updated to match that baud rate (see the example.cfg
file for details). For example:

@ -114,6 +115,11 @@ The baud rate shown on the OctoPrint web page has no impact on the
internal Klipper micro-controller baud rate. Always set the OctoPrint
baud rate to 250000 when using Klipper.
The Klipper micro-controller baud rate is not related to the baud rate
of the micro-controller's bootloader. See the
[bootloader document](docs/Bootloaders.md) for additional information
on bootloaders.
### Can I run Klipper on something other than a Raspberry Pi 3?
The recommended hardware is a Raspberry Pi 2 or a Raspberry
