The MyRate device is based around an Atmel AT91SAM7S256 processor running at 16 MHz, which includes 256 KB of embedded flash and 64 KB of onboard RAM. However, that just scratches the surface of this device’s hackability.

Next to the Atmel CPU is another fine Atmel product, an Atmel AT26DF161A 16MB flash chip.

There is one more Atmel chip on this board hiding under the connected daughterboard. I could only make out the Atmel logo on it without desoldering (which I may do later to figure out what this chip is).

There’s a white CSS-J4B20 buzzer on the top as well. What this is supposed to alert you to is completely up in the air at the moment.

There is also a 64 KB Oberthur SIM card. What data this stores (other than standard stuff) is unknown at the moment, as I don’t have a SIM card reader.

Turn the device over and there’s a cell phone module: a Telit GE864-QUAD with an antenna stuck on top with some double sided tape.

Now for the really interesting stuff. There is a 4-pin header on the top side of the device. Since the processor supports JTAG, it’s safe to assume that this is a JTAG header with the VCC and GND pins missing. Maybe?

Most of the chips used in the MyRate device, except for a mystery Atmel chip hiding out under the daughterboard.

Are there really JTAG pins on the MyRate device?
