Lynkr is an independent engineering consultancy (SASU) founded in Toulouse by Michaël Ughetti, an electronics engineer with 18 years of experience in R&D and industrial production.
Our approach covers the entire product lifecycle: from specification through schematic design, layout, firmware, qualification and regulatory certification all the way to series production.
Whether you are a start-up launching your first connected device or an established manufacturer optimising an existing product line, Lynkr brings deep technical expertise without the overhead of a large engineering firm.
“Dual competence in R&D and production engineering ensures every design is production-ready from day one.”
Managed a full SMT production line (screen printer, pick & place, reflow oven) for 15 clients, designing 10+ boards per year across a broad range of applications.
Power simulation (LTspice, MPS Designer), 3D mechanical integration (Fusion 360), PCB design with Altium Designer.
Multi-protocol expertise: LoRa, BLE, Wi-Fi, ZigBee, 4G/5G, NB-IoT. Antenna design and radio qualification.
