The ADI LoRa reference design is an Arduino-like development platform based on the MAX32670 ultralow power microcontroller (MCU) with integrated power management for processing, control, and connectivity. The MCU system is based on the ARM Cortex-M4 processor, a collection of digital peripherals, embedded SRAM and flash memory, and an analog subsystem which provides clocking, reset, and power management capability. The MAX32670 features industry leading ultralow power, which makes it ideal for Internet of Things (IoT) applications.
The platform comes in an Arduino Uno form factor, with two PMOD connectors, and an ESP32 Dev Kit connector for easy-to-connect sensors and signal conditioning add-on modules. The on-board LoRa connectivity makes this board IoT-ready right out of the box. The solution is complete with working software and hardware, as well as software examples.
The base platform is accompanied with various Analog Devices add-on hardware but is also compatible with 3rd party hardware. A free programming and debugging tool called Maxim SDK is also provided by Analog Devices.
Each sub-section contains a general description of the board, detailed description of the connectors, jumpers, and buttons (if any). It also provides links to the design support files (schematics, bill of materials, design projects, and technical documentation), as well as internal links to the example demo software projects.
The MAX32670-SX-ARDZ LoRa Baseboard consists of the MAX32670 high-reliability, ultralow power microcontroller based on Arm Cortex-M4 processor, and the LoRa RF transceiver module targeting SX1261.
In order to use this baseboard, all hardware settings such as the hardware peripheral connections, jumpers and UART switch configurations, power configurations, connectivity options, and the USB connectors and programming connections are provided in this page. Links to the schematics and the layout files are also available below.
The EV-FLOWMETER-ARDZ is an ultrasonic time-of-flight (ToF) flow meter that sends and receives ultrasound waves between piezoelectric transducers in both the upstream and downstream directions in the pipe. By measuring the TOF difference between the upstream and downstream wave travels, utilizing sophisticated digital signal processing techniques, a very accurate flow rate can be calculated.
The MAX35101 is the center of the heat/flow meter system. The MAX35101 integrates all the functions required for automatic ToF measurements, including the ultrasound pulse launching and detecting, TOF calculation, temperature measurement, and a real-time clock (RTC). The MAX35101 can work in various configurable automatic event timing modes, requiring very minimal interactivity from a host microcontroller, thus reducing the total power consumption of the system.
The EV-ADE9000SHIELDZ is an Arduino shield compatible with Arduino Zero. The shield can be directly interfaced with current transformers and voltage leads. It enables quick evaluation and prototyping of energy and power quality measurement systems with the ADE9000. Arduino library and application examples are provided to simplify implementation of larger systems.
The end node is EV-STRUCTURAL-ARDZ, which is a vibration sensor that uses the ADXL343 digital output MEMS accelerometer chip and ADIS16203, a programmable 360° inclinometer.
Aside from providing vibration data, it also has a digital temperature sensor using MAX30210 that gives the option to shut down sensitive machines and equipment for smart motor sensing application.
The sensor detects as well if the horizontal position of the sensor changes, which points towards a collapse of the structure where the sensor was deployed.
