Lora Reference Design
Introduction
The 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.
