Ruben Crispino

Versatile engineer, with a PhD, focused on electronics, product design and research-oriented devices.

I can follow projects starting from a simple idea to a fully functional prototype and straight into production. I can help you with what is important at each step.

I design, build, program, and test prototypes with in-house tools and instruments.

Key offerings:
• System analysis and design
• Circuit simulation / LTspice
• Electronics design and printed circuit board (PCB) layout with Kicad
• Mechanical 2D and 3D CAD work to supplement the electronics or to realize ad-hoc structures and enclosures
• Embedded firmware development
• Build and test prototypes
• Manage product manufacturing and logistics
• Troubleshoot and fix failed devices and bad designs.
• Labview applications
• Matlab scripts

I have developed a wide variety of circuit boards, including:
• Industry standard 4- and 2-layer boards with surface mount and through-hole components
• Products incorporating Bluetooth, BLE, WiFi, LoRa and serial interfaces (SPI, I2C, LIN, RS-232, RS-485)

Whether it's taking an existing prototype and turning it into a manufacturable product, or developing a brand new product from the early concept stage, I enjoy providing you with technical solutions that are suitably engineered for your needs.

Main Electronics Experience:
• Low power battery-operated devices
• Microcontrollers
• Motor controls
• Analog circuits
• Wireless/Bluetooth design,
• RFID systems,
• Sensor solutions
• Product security (encryption)
• Embedded programming C/C++.

Please get in touch and I'd be happy to talk through your job.
