1. Description

The uCAM-II (microCAM-II) 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.

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-II 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 (80x60 to 160x120) single frame raw

images for viewing or high resolution (160x128 to

640x480) JPEG images for storage or viewing.

The uCAM-II 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-II

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.
