SWEEL SX2 is an GPS tracker base on Ultra Low Power SX1276/1278 SIM Module.
SWEEL SX2 includes a low power GPS module and 9-axis accelerometer for motion and orientation detection. The power for both of the GPS module and accelerometer can be controlled by the MCU to achieve the best energy profile for different applications. SWEEL SX2 is powered by rechargeable 1000mAh Li-on battery. You can program the device to work from weeks to months depends on the target use case.
The SWEEL SX3 is pre-loaded with a Sweel firmware.
