The primary design goal of the Nano G2 Ultra is to reduce power consumption and improve battery life by using the low power MCU NRF52840 and optimizing the power related designs. The typical battery life is optimized to be about 5 days. Nano G2 Ultra and Nano G1 Explorer have exactly the same Lora front-end circuit design and internal wideband Lora antenna, which supports frequencies from 815 Mhz to 940 Mhz. The wideband antenna, combined with an optimized wideband Lora RF frontend circuit, enables the Nano G2 Ultra to work with the majority of regions’ LoRa frequency bands around the world without the need for antenna changes.
