LoRaONE is a tiny Arduino compatible IoT development board in the size of a matchbox. The board connects everywhere through LoRa technology. Developers can place it anywhere and create anything they can think of – build a weather station, control street lights or get a signal when they have received (snail) mail.
The board is powered by a ATSAMD21G18, 32-Bit ARM Cortex M0+ microcontroller. It includes Microchip’s RN2483 or RN2903 LoRaWAN module.
The development board has built-in GPS and accelerometer/magnetometer sensors to track the location, movement, and detect magnetic fields. It also features 14 I/O pins to connect other sensors or devices.
A solar charge controller that runs on a LiPo or permanent battery offers up to 500mA charge current. The module uses a very small GPS module, the Ublox Eva 7M,
The GPS sensor is a u-blox EVA 7M designed to use less power than many of the GPS sensors available on the market. It uses the assisted GPS feature to get a fix in just seconds. The accelerometer/magnetometer sensor is an LSM303D, which combines a digital 3-axis accelerometer and 3-axis magnetometer into a single package.
The low power Accelerometer/Magnetometer chip allows the board to remain in sleep mode until it detects motion or has a change in magnetic field. This is crucial for developing applications with low power. For instance, it can be used to conserve power by turning on the GPS devices only when motion is detected.
The Magnetometer can be used to develop a range of applications, such as a parking sensor which can detect if a car is parked with changing magnetic field, or to determine if the gate is open or not.
The LoRaONE measures only 40×25 mm and can be fitted almost everywhere. The board can be programmed via the Arduino IDE.
