1 Overview This document describes the hardware of the Smartico Industrial Sensor LoRaWAN. The sensor has a wide range of peripherals that can be used by the user in their own applications. The functionality of the device depends on the application that is integrated and launched in the device. This document does not describe the functionality of the device, but only contains a description of the technical parameters and capabilities.
3.1 Communication board The sensor communication board is the main device and contains the microcontroller, wireless interface, and user interface. The main elements of the communication board are shown in the Figure 1. Figure 1: Communication board view Table 2: Description of the Communication Board components Component / Interface Description Integrated ISM Band antenna A high performance antenna for the ISM bands 868/915MHZ Smartico LoRa Module Certified radio module of SMARTICO LLC own design.
GND - Ground Flexible Cable 3.2 This cable connects two boards: Communication and Extension Board Extension board The Extension Board contains a set of various I/O interfaces (digital inputs, analog inputs, serial interfaces). Also, this board can contain a power supply from an external source and a power manager. The power manager allows the device to automatically switch power to the internal battery when the external power is lost.
RS485/232 Serial Interface 1-WIRE Interface Power Supply for Ext. sensors Outputs Battery DC/DC Power Convertor (optional) Battery Connector The interface is intended for communication with external devices via the RS485/232 bus. This interface can be either RS485 or RS232, depending on the equipment ordering option. Standard digital 1-WIRE interface is designed for communication with external devices (such as temperature sensors, i-Button, etc.) This output is intended for supplying external sensors.

Figure 4: Activating the device with a magnet 4.2 Data cable connection To perform the initial settings of the device or to update the firmware, you must connect the data cable to the Communication Interface, as shown in the Figure 5. Make sure the marker on the data-cable is in the correct position. User Manual SMARTICO LLC. Version 1.0.
Figure 5: Data cable connection After pressing the B1 button once, the sensor wakes up and is ready for via the date cable. For a detailed description of setting up the device, see the documents of AT Commands Description and App Description. User Manual SMARTICO LLC. Version 1.0.
4.3 Installation User Manual SMARTICO LLC. Version 1.0.
4.4 Firmware Upgrade The device supports secure firmware updates. The firmware file is loaded encrypted and unpacked after being downloaded to the device. Only after checking the integrity and authenticity of the firmware, the update process begins. When updating via data cable, the firmware file is transferred to the SENSOR using the standard XMODEM file transfer protocol. To complete the process of updating the firmware via the data cable, you must perform the following sequence of actions: 1. 2.
After selecting the file, file transfer procedure will start as shown in the figure: After the successful transfer of the firmware file, the firmware update procedure will begin: User Manual SMARTICO LLC. Version 1.0.
After completing the firmware update procedure, you need to check the current version by running the command: AT+CGMR FCC Statement 1. This device complies with Part 15 of the FCC Rules.
