The C3 CAN bus display, formerly the CANvu 355/Veecan 320, is a second generation compact color display from Veethree. It is designed as an OEM (Original Equipment Manufacturer) product, and is not available direct to end users.

The C3 has a 3.5inch color display with fully integrated input and output features including 7 analog inputs, 4 relay outputs combined with 2 digital inputs, 1 tachometer, 2 CAN input connections (supporting SAE J1939, NMEA 2000), plus a USB port it is part of the compact, flexible, and rugged CAN bus display & monitors from Veethree.

The QVGA color display can be viewed in full sunlight, and the unit is totally sealed and electronically extremely durable. The C3 monitor is equipped to meet the challenge of providing tough, flexible, maintenance free instrumentation in even the very harshest of environments.

Programmers can quickly assemble a custom application project using the proven Veethree software development kit (SDK) which includes access to the Veethree component based software library. The fully developed software is then able to be rapidly validated on a PC using the built in simulator. Alternatively our in-house software development team can develop bespoke applications on your behalf working with you as an extension of your own engineering team.
