Catfish hardware

The catfish hardware is based on the Qualcomm MSM8909w chipset. In the picture of the front of the main board with the shield removed, this part is just above the horizontal center line of the board and slightly to the left of the vertical center line. The large part under the bit of rubber or glue is a Kingston 04EPOP04-NL3DM627, which is a combo memory of 4GB MLC + 4Gb LPDDR3 in a 136-Ball BGA package.
