IoT Appliance using ESP32 and SIM808

We are developing an IoT appliance for a specific use. The first generation of the appliance will use a GSM and GPRS network to manage and collect information from an operating environment. We will also need geolocation information. We have a concept test device (PoC) that works on the breadboard using ESP32 and SIM808.

We are now searching an embedded systems engineer to create a prototype appliance, power suply, schemas, PCB and help us designing a project to manufacture a prototype system.

This prototype will be used in a pilot project with 30 users. If the pilot project will approved to "Go" , we'll also need engineering support to create a final appliance
