The C3l CAN bus display, formerly the CANvu 355 LP/Veecan 320 LP is the Low Profile model in the range of 3.5″ compact color CAN bus displays.

The C3l is designed as an OEM (Original Equipment Manufacturer) product, and is not available direct to end users. It is a fully sunlight viewable 3.5inch color display, which is compact and highly flexible with a low profile bezel. It has a larger more accessible and stylized keypad, which is backlit for ease of operation at night.

Electrically and environmentally rugged, the C3l CAN bus display has a high brightness QVGA (320 x 240 pixels) color LCD which is fully sunlight viewable and the unit is totally sealed (IP 67 all round, IP 66 front) ready to meet the challenge of providing tough, reliable, and maintenance free instrumentation in harshest of environments.

On board is a Freescale iMX 286 ARM processor running Linux, and programmers can quickly put together a project using our proprietary software developer's kit (SDK) and the proven Veethree component based library. Application software is able to be rapidly validated on a PC using the PC simulator.
