Electronic design is at the heart of R&D, aiming to meet the requirements of the specifications. Electronic design starts with an idea, progresses to a schematic, and ends with computer-aided design (CAD) to create an electronic board. Our role is to ensure the performance, reliability, and compliance of our circuits with functional and regulatory requirements.

Here are the main steps of electronic design:

• Needs analysis: Identifying the functions to fulfill, technical constraints (voltage, current, environment), and applicable standards based on the specifications.
• Schematic design: Developing the functional schematic by selecting components (microcontrollers, sensors, resistors, etc.) and defining their logical interconnections.
• Simulation: Using simulation software to validate circuit behavior before physical realization.
• PCB (printed circuit board) design: Creating the routing plan with electronic CAD software, considering space constraints, electromagnetic interference, and thermal dissipation.
• Component selection: Choosing components based on technical specifications, availability, and cost.
• Prototyping: Producing prototype electronic boards for real-world testing.
• Testing and validation: Verifying circuit functionality, compliance with specifications, and making necessary adjustments.
