RAK8211-G iTracker all in one IoT Tracker Module with GPRS Sensor node (Quectel M35 based) with BLE, GPRS, GPS and Sensors

iTracker RAK8211-G is versatile developer board aimed at aiding in quick prototypes using GPRS. The board includes a vast array of connectivity options (GPRS, BLE 5.0 and GPS) and sensors like an accelerometer, a light sensor and a barometric sensor. At the heart of the module is the venerable Nordic NRF52832 BLE processor. The GPRS connectivity is provided by the Quectel M35 module. The iTracker module is Arduino friendly and can be programmed using the IDE.

The board also provides SWD interface for programming the NRF52832 core. The combination of BLE and NB-IoT provides flexible low power consumption development along with myriad of application option ranging from telemetry to live tracking and environment sensing.
