March 8th, 2010Neo FreeRunner from Openmoko
January 20th, 2010Neo 1973 was first first major open hardware platform by Openmoko. Neo Freerunner was follow up of Neo 1973. Building open hardware mobile is challenge in itself. Primary because GSM chipset vendor do not provide small quantity of baseband chipset & would also not like to provide support for same.
Neo FreeRunner uses ARM9 processor based SC32442 from Samsung. FreeRunner is complete smartphone with LCD, Bluetooth, WiFi, GPS, Accelerometer besides GSM Baseband support for call & GPRS.
Neo FreeRunner is support by multiple Linux distribution & holds capabilities to support multi boot, This is clearly big feature on smartphone. Neo FreeRunner provides good platform for developing any hardware or software for Smartphone. Schematics, hardware reference manual etc are available to community for use.
Odroid : Entertainment Device
January 10th, 2010Odroid is developer focused entertainment / gaming device. It comes with schematics & includes itś support in Linux & Android.
Odroid contains Samsung S5PC100 SoC, which contains ARM Cortex-A8 833MHz processor. This gives healthy competition to Beagleboard, which contains ARM Cortex-A8 of 600 MHz.
Quick Pros:
- ARM Cortex-A8 833MHz processor. 512 MB RAM, Touch screen & HDMI output, WiFi, Bluetooth gives big advantage over Beagleboard in terms of hardware capability.
- Odroid is more useful as complete device rather than as reference platform. Thus, It is easy to developer software over it & use it.
Quick Cons:
- Odroid is released much latter than Beagleboard, thus odroid community is less active compare to Beagleboard.
- Odroid has little option to interface external piece of hardware such as any sensor.
- Priced at 349 USD, Quite premier & out of reach for many.
