It so sad when they expose the guts of devices like the Chumby One. The Chumby has personality, you know? You kind of feel for it? Oh well. iFixIt tore the Chumby into little bits, splaying the processor, screen, and even the speaker for all to see. There’s not much to see here but the motherboard features:

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

This means there is plenty of room in here as well as a potential for adding your own firmware to this little fellow, thereby breaking him free of the Chumby chains forever. You can read the whole thing right here, but it will just make you sad.
