Expansion Module
Adding functions for controllers
NORVI is always about on connectivity and expandability. This is the time to make use of Expansion port of NORVI Controllers.
The series of expansion modules connects to NORVI IoT controllers via its I2C and UART connections. You can add more features to the NORVI Controller without huge customizations. NORVI provides true technology with reliability for industrial applications being worlds iot hardware manufacturer.
We have included NB-IoT, LoRa and analog modules as expansions.
Daisy-chain up-to 6 expansion modules
