Adafruit Feather M0
Introduction
In addition to using the Particle Boron or Argon and Raspberry Pi for data logging with 3D-PAWS, the Adafruit Feather M0 Adalogger is a versatile alternative. This compact all-in-one board combines a powerful ARM Cortex M0 processor with built-in USB, battery charging, and an onboard microSD card slot for reliable local data storage or LoRaWAN/Wifi connectivity.
It can be used with the same Grove Shield FeatherWing for Particle Mesh to integrate sensors easily, providing a flexible and portable solution for environmental data collection and logging

The Adafruit Feather M0 Adalogger comes in a few different varieties depending on communication needs. Use the following software with the appropriate device:
For LoRaWAN and Wifi connectivity:
For a no network device that saves the data to the SD locally:
This device needs an external real time clock (RTC). We recommend the DS3231.
Firmware Variants for Different Product Applications
We offer specialized firmware for different 3D-PAWS products to ensure optimal performance for a range of environmental monitoring applications. Please refer to our Github for the most recent firmware releases: https://github.com/3d-paws. All products for these boards begin with 3D-PAWS-FEATHER-XXXXXXX.
Storm Surge and Wind Product: This product uses a measurement interval and data processing approach that aligns with NOAA’s National Ocean Service Center for Operational Oceanographic Products and Services (CO-OPS) specifications. In accordance with CO-OPS standards, the firmware is configured to acquire and store water level measurements every six minutes, using an average of discrete samples centered about each six-minute mark. This interval and methodology ensure compatibility with national data networks and support high-quality, standardized data collection for coastal and oceanographic monitoring.
Ultra Low Power Stream and Snow Gauge Product: Designed for remote locations where power efficiency is critical, this firmware minimizes energy consumption while reliably logging stream or snow depth data. The ultra low power mode is ideal for battery- or solar-powered deployments in difficult-to-access areas.
Feather LoRa Remote Units for Soil, Rain, and Distance Sensors
We also support remote sensor units built with Adafruit Feather boards equipped with LoRa radios. These remote units are designed for low-power operation in the field and can be used with soil moisture, rain, and distance (stream or snow) sensors. Each remote unit transmits its sensor data wirelessly over LoRa to a central “Full Station.” The Full Station, typically a Particle Boron, acts as a gateway: it receives LoRa data from multiple remote units and then relays that data to the Particle Cloud using its cellular connection. This architecture enables reliable data collection from widely distributed sensors, even in remote locations without Wi-Fi or direct cellular coverage at each sensor site.
