MicroCAM 3  (uCAM-III)

The uCAM-III (microCAM-III) is a highly integrated serial camera module which can be attached to any host system that requires a video camera or a JPEG compressed still camera for embedded imaging applications, and is the new upgrade to the popular uCAM-II, which is backwards compatible but includes some additional features.

The module uses a CMOS VGA colour sensor along with a JPEG compression chip that provides a low cost and low powered camera system. The module has an on-board serial interface (TTL) that is suitable for a direct connection to any host micro-controller UART or a PC system COM port.

The uCAM-III is capable of outputting both RAW format and JPEG format images.

User commands are sent using a simple serial protocol that can instruct the camera to send low resolution (80×60 to 160×120) single frame raw images for viewing or high resolution (160×128 to 640×480) JPEG images for storage or viewing.

The uCAM-III comes in a compact form factor with a built in lens and a 5-wire connector that provides easy access to both power and serial data.

There are 3 lenses available for this camera from 4D Systems. A 56 degree (Standard), a 76 degree, and a 116 degree.

These are available to purchase from 4D Systems separately if required. The uCAM-III ships with the 56 degree lens installed.

There is a locking nut on the barrel thread of the lens, which is used to lock the focus in place once set, to prevent it from inadvertently being changed.
