[Elecraft] Raspberry Pi (a 35 dollar Computer) Linux and Elecraft K3, K2, KX3 etc

[Holger Schurig]

They Raspberry Pi may be fine. Or it might be not. Because it's an
extremely limited device.

For example: doesn't have an Audio- (Mic/Line) input. So you need an
USB dongle for it if you want to do any data mode stuff (e.g. with
FLDIGI).

Doesn't have an RTC clock, so always starts at 1st January 1970 on every boot.

Broadcom, the manufacturer of the CPU/SoC combo, is a
kind-of-secretive company. They often don't provide chip
documentation. For more than 7 years the Broadcom WIFI-Chips in the
Linux WLAN stack have been inferior to, say, Intel or Atheros chips.
And yeay, the do that again: you don't get a full datasheet for the
BCM2835 that is used in the Raspberry PI. If you really want the docs,
you need to sign an NDA with Broadcom. But they are snoop: you need to
provide a business model and declare how many chips you will buy from
them. Compare with with TI, for the TI OMAP, where you almost get
everything, downloadable from their Website without registration or
NDA.
