BlueShark

BlueShark modules are based on OMAP35xx processors from Texas Instruments. These modules evolve from 2009 running a series of versions ver.1, ver.2, ver.3, ver.4. Presently only versions v3.1 and v4.2 are in production. They differ in Ethernet controllers:

• v3.1 has SMSC LAN9221 - very powerful and fast (upto 7MB/sec)
• v4.2 has Micrel KSZ8851-SNL - power efficient and slow (upto 1.25MB/sec)
