Some interesting features of the board include:

• 64 MB Hynix HY5DU121622BTP CMOS Double DataRate (DDR) Synchronous DRAM
• GL8520G USB 2.0 Hub
• MMA7455 3-axis accelerometer
• QN8005B FM radio
• Blank space for NAND flash (not used due to booting from MicroSD)
• MicroSD socket complete with a 2GB Kingston MicroSD firmware card
• Unpopulated passives for composite (NTSC/PAL) video output

Now, back to disassembling the chassis...

A simple tug removes the Ralink-based RT2571 USB Wi-Fi dongle.

• The Ralink RT2571 supports both USB 1.1 & 2.0 for 802.11 a/b/g connectivity.
• The chipset has the capability to operate in Windows XP, 2000, ME, 98SE, and in Linux.

Considering the open source nature of the chumby, wireless internet can conceivably be sacrificed for the extra USB port housing the Wi-Fi dongle.

Get your groove on with the single 2W mono speaker mounted flush in the plastic chassis.

After removing the four Phillips screws securing the speaker to the chassis, use a sharp blade to carefully separate the speaker cables from the adhesive applied near the speaker opening.

• The speaker wires are glued down to avoid any rattling noises from ruining your air guitar solo.

The speaker has a 7/8" concave aluminum diaphragm held to the frame with a foam rubber surround.

The white panel on the chassis is fitted with a conical port presumably to eliminate resonance.
