With M3 fixing screw holes for easy installation and fixing.

After power-on reset, MLX90614 is the factory default output mode SMBus, and PWM is not enabled. The SCL pin needs to be kept high at power-up to use PWM. If PWM has been enabled, you need to switch to SMBus and reconfigure the PWM/SDA pin before starting SMBus communication. Need to keep the SCL pin for more than the request time (tREQ) >1, 44ms to keep it low. In this case, the data on the SDA line is ignored. Once PWM is not enabled, it can only be enabled by cutting-off the power supply or exiting sleep mode. If PWM is not enabled through EEPROM, the PWM/SDA pin will be directly used for SMBus communication after POR. In this case, there is no need to send the request status. The way to enter SMBus mode from PWM or thermal relay is the same
