4.1.7. AmbiMate connection to MCUs
AmbiMate MS4 sensor module is connected to SENTIMATE MCUs (the two microcontrollers integrated in the Silicon
Labs wireless modules) through I2C, analog and digital signals; here in after is reported the pinout of the AmbiMate
module.
Below the table of the connections on the MGM13P 2.4GHz module and on ZGM130S Z-Wave module. Both the SoM
have inside a Cortex-M4 microcontroller and can manage the sensor module itself independently from each other.
