The Odroid C1 (http://hardkernel.com/main/products/prdt_info.php) is an interesting single board computer because it has the same form factor as the Raspberry Pi at about the same price but with the following features:
- four 1.5 GHz CPUs versus one 0.7 GHz CPU
- gigabit Ethernet as well as 1/100
- a gig of RAM instead of half a gig
- a realtime clock
With the removal of a Raspberry Pi dependency in 1.19 you can now install dump1090 and piaware in the same manner as you would on a Raspberry Pi, and since the Ubuntu version of Linux the Odroid uses is built on top of the same Debian version of Linux that the Pi uses, it’ll work.
You’ll need to blacklist the RTL-SDR dongle. You can do this by adding a line to /etc/modprobe.d/blacklist.conf that reads
blacklist dvb_usb_rtl28xxu
. You can immediately break the association between the TV driver and the RTL-SDR by issuing a sudo rmmod dvb_usb_rtl28xxu but this will not survive a reboot.
The Odroid isn’t a perfect replacement for the Pi… for instance the Odroid is powered via a small barrel connector rather than the micro USB, necessitating a different power solution, and it has a micro HDMI connector as opposed to the full-size one on the Pi, plus we feel like the supply of Raspberry Pis is much more assured than the supply of Odroids, but with all that extra CPU and the extra memory the Odroid can simultaneously support a desktop environment with fairly decent performance, considerably better than the Pi, so for the intrepid experimenters among you with an interest, you might consider the Odroid C1.
