The ARM PICO is the new family of ATIM modules. Its size was practically divided by three compared to the ARM NANO family to answer user’s need who wish to reduce sensors size. The two families share the same functions, which allows to keep compatibility between modules. The P8SIG is a transmitter operating either SigFox or locally. It integrates the RTU controls allowing pressed users to develop a product quickly without the need for external microcontroller.
