Hello, my name is Juan Jacinto Montenegro, and I am an electronic engineer at Rother.
We have contacted STMicroelectronics to obtain recommendations regarding their products for our IoT project. They have suggested that we contact their distributors.
Our project focuses on the automotive sector, both in the civil and military fields. For this project, we need to meet a series of specifications:
-UART or USB2.0 Full-speed communication interfaces to communicate with our microcontroller, which will act as a host controlling the IoT modules.
-Wi-Fi and cellular (LTE 4G/5G) connection for sending data via HTTP and MQTT to a remote server.
-Sending SMS messages and voice calls
-Support for GNSS geolocation.
-Interface for connecting a MicroSD card and storing local data.
I would like to know if you have any IoT modules or boards that meet these requirements. Initial testing would serve to validate the results obtained and, if these were satisfactory, we would proceed to purchase the different products tested (cellular module, WI-FI module...) to design our own board.
