Veronte CEX-CEM Expander

Veronte CEX is a powerful peripheral that extends the I/O in Veronte Autopilot by making it possible to relocate and to group sensors, actuators, payloads, motor controllers… at the time permitted to reduce the amount of cable in autonomous vehicles and the risks of electromagnetic interference.

Veronte CEX’s integration is simple and easy, which makes it a quick solution for increasing connectivity and allowing wiring optimization in large vehicles. In the CEM version, Veronte CEX is embedded in an aluminium case which provides high resistance to impacts and IP66 and electromagnetic interference protection.

With Veronte CEX, the data capacity for input and output in Veronte Autopilot is highly increased. Its advanced design makes it possible to control several peripherals (PWM, UART, Digital Output, I2C, Analog Inputs…) through a redundant CAN Bus.

It can be used to expand the I/O capacity in Veronte Autopilot or to control peripherals with a robust communication protocol. If needed, it is possible to install several Veronte CEX boards in the same network to increase the number of I/O ports as per system architecture needs.


Wiring Optimization


In a sector where weight is such an important agent, wiring is one of the most common struggles faced during drone design. Veronte CEX uses CAN Bus for long distance cables (autopilot to CEX) and leaves less robust signals only for short cables close to the peripherals (CEX to device).

This robustness makes the system resistant to electromagnetic interference and permits the installation of long cables without signal loss. Furthermore, it includes redundancy with CAN Bus isolation, making the system operational even in case of a CAN Bus break of line.

Safety is a critical factor in the drone industry, especially when focusing on a UAV Certification. Redundancy is a basic feature for any system which is a candidate to pass exams and tests with demanding safety levels, remaining operational even in case of a CAN Bus break of line.

The redundant CAN Bus includes galvanic isolation, in order to avoid the propagation of electrical failure in the system. In the case that one of the lines became affected by an electrical issue, the other CAN Bus line will remain operative and unaffected.

CEM Protection


Veronte CEM is the most robust version of Veronte CEX. This versatile I/O expander includes an aluminium protection to make the system resistant to shocks and environmental conditions. The aluminium enclosure for EMI protection with an IP66 waterproofness level.

Besides the aluminium protection in CEM, it also includes some additional signal converters to customize the I/O in the Can Expander. UART ports in CEX can be converted to RS232 and RS485 in different configurations. Please ask in case custom I/O is needed.
