I. ITTIA × L&R Ingeniería Partnership (2025–)

ITTIA and L&R Ingeniería have been building a working partnership since 2025. ITTIA is an established US-based software company (ITTIA blog) and an STMicroelectronics Authorized Partner: their ITTIA-DB package is a production-grade database platform to deploy deterministic, power-fail-safe data management on STM32 microcontrollers. L&R Ingeniería brings embedded hardware design and firmware expertise with field experience in systems throughout Patagonia. Together we offer production-grade edge data intelligence on STM32. Upcoming workshops will demonstrate these capabilities based on an L&R Ing. METEO module connected to STM32H573I-DK, FreeRTOS and ITTIA-DB-Lite v9.3 + Analitica.
