I want to build a prototype which does the following things: 1) position detection via GPS 2) transmission of position data to remote server 3) data connection on GPRS - GSM - 3G-4G mobile network 4) installation on a mobile offroad vehicle powered by 12V 5) continuous (1 x minute) weight detection (low precision required) from a load cell from 0 to 50 kg 6) detection of 8 opto-isolated digital inputs 7) 8 relay outputs 8) low cost display 10 " or 12" high brightness colors 9) power down on power off and autoresume on power on from ignition key 10) connection between close devices ( at most 100mt ) of the same fleet through some RF (wifi, Lora, ..) at low power 11) small autonomous battery The device must be functional at a prototype level using commercially available hardware. The firmware must be written preferably in C / C ++. I will evaluate solutions with alternative languages. The microcontroller must be 16 or 32 bits. I prefer that you use texas instrument MSP32 and / or Espressif ESP. I will evaluate solutions with alternative controllers. The system must be designed to operate on cars.

I'm an italian electronic engineer with more than 15 years of work experience. I work as HW designer; FW and SW developer. As HW designer, I work in Altium, KiCad and Orcad and I have experience in development single MCU (Microchip PIC and ARM Cortex) boards with several digital I/O (GPIO, UART, SPI, I2C, PWM,....) and some analog I/O. I design complete board: power section, MCU section, peripheral section,.... I design also boards with battery power; so I have experience in low power PCB design. I have also experience in commercial boards (Arduino, Raspberry, Beaglebone,...) shields design. I have also experience in bluetooth (both 2.0 and 4.0) PCB design. As FW developer, usually I work in C for Microchip PIC (MPLAB X + XC compilers) and Eclipse + GNU ARM for different ARM Cortex M3/M4 manufacturers (STM32Fx, NXP, EFM32 SiLabs, but I'm ready to learn new frameworks). I work both single task and multi task environment (FreeRTOS and RTX). I write code both for low level driver (GPIO, UART, SPI, I2C, PWM....) management and for high level/final application. I work also in "C code" commercial boards Arduino/ESP8266 and Linux embedded commercial boards (Raspberry and Beaglebone). I have also experience in bluetooth (both 2.0 and 4.0) programming. As SW developer, I work in C, C++, .NET, Java, and lot of others programming languages. Mainly I work for Windows O.S., but I have experience in Linux development too.
