Meet the Smol Slimes, also known as nRF Trackers, the next evolution in compact, power-efficient motion tracking! Built on Nordic Semiconductor's nRF52 series System-on-Chip (SoC),these trackers deliver robust, low-latency communication with exceptional power efficiency. Powered by a compact 130 mAh battery, Smol Slimes can last for days or even weeks-far surpassing traditional ESP (WiFi-based) SlimeVR trackers-making them perfect for extended use in VR, wearables, and IoT applications. Equipped with LSM6DSV Inertial Measurement Unit (IMU) and a QMC6309 magnetometer, Smol Slimes leverage the open-source VQF fusion algorithm for on-device sensor fusion. Thanks to meticulous integration and tuning by the SlimeVR community, these trackers minimize drift and deliver highly accurate motion data tailored to specific use cases. A receiver (Recommended HolyIOT-21017, but not included) is required to connect the trackers to the SlimeVR Server, and while standalone Quest-headsets are not directly supported, connectivity is enabled via OSC (Open Sound Control) through a paired computer. Features: Nordic nRF52 SoC : Ensures low-latency, power-efficient communication for reliable tracking. LSM6DSV IMU: Advanced motion sensing for precise acceleration and angular rate measurements. QMC6309 Magnetometer: High-accuracy magnetic field detection for dependable orientation tracking. 130 mAh Battery: Ultra-efficient, offering days to weeks of operation in a compact form.
