I own a Cameo, but I don’t know if it’s a 1, 2, or 3.
The Cameo 1 has a monochrome LCD display, push-button controls, and accepts an SD card.
The Cameo 2 features a full-color LCD touchscreen and accepts a USB flash drive.
The Cameo 3 features a full-color LCD touchscreen and a dual-blade carriage. When the cover is closed, all controls are hidden.
