Logitech LS1 Laser Mouse

 

Sensor Markings:

S7550

80826T

2AV

 

Looks like this one is an ADNS-7550: www.avagotech.com/pages/en/navigation_interface_devices/n...

 

The controlling chip+USB interface:

CY7C63813-PXC

C56632AF

PHI0837 A O4

647813

 

It's a Cypress Semi part:

- has an internal oscillator (yay!)

- 8K Flash/256 Bytes RAM

 

Assuming it can be wiped & reprogrammed with the Cypress PSoC tools, there's some serious hack potential here! Change some of the buttons into sockets and soft-configure as outputs.
