Teardown of the Canon PowerShot A3100 IS point-and-shoot camera.
12.1 MP, 1/2.3" CCD sensor, optical image stabilizer. Released in January 2010. PCB date code is 3rd week of 2010.
The teardown subject was dead, with missing battery, and won't power on when 3.7V is applied to the battery terminals.
Technical details, including firmware dumps, on the CHDK Wiki.
No service manual found.
