Oura Ring 5 teardown reveals ARM chip, 384 KB RAM and impossible repairs

The Oura Ring 5 has been found to be 40 percent more compact than its predecessor, offering greater comfort to its users. This compact design is achieved through the flexible mainboard and the 10.2 mAh battery, which make full use of the space inside the ring. The smart ring is based on an Ambiq Apollo 3 Blue Ultra Low Power SoC, which features an ARM Cortex-M4 processor core. The Oura Ring 5's battery life is said to last between six to nine days, providing users with a reasonable amount of time before needing to recharge. However, the ring's design has been found to make repairs impossible once the battery reaches the end of its life, essentially making it electronic waste. The teardown of the Oura Ring 5 reveals that it has 384 KB of RAM, which is a notable specification for such a compact device. The use of an ARM chip in the Oura Ring 5 is also significant, as it provides the necessary processing power for the device's various functions. Despite its compact design and impressive specifications, the Oura Ring 5's lack of repairability is a significant concern for users who are looking for a more sustainable option. The ring's design and specifications are a testament to the advancements in technology, but also highlight the need for more environmentally friendly designs. The Oura Ring 5's features and specifications make it an interesting device, but its limitations and lack of repairability are important considerations for potential users.
