Description:Introducing Smol Slimes, also known as nRF Trackers, the next upgrade 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 ST 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 (HolyIOT-21017: Highest performance for highest price. Reported to have significantly higher signal strength than other options due to included amplifier.) 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.ST LSM6DSV IMU: Advanced motion sensing for precise acceleration and angular rate measurements.QMC6309 Magnetometer: High-accuracy magnetic field detection for dependable orientation tracking.NH-B2020RGBA-HF: RGB LED is used for tracking status indication.130 mAh Battery: Ultra-efficient, offering days to weeks of operation in a compact form.On-Device VQF Fusion: Open-source algorithm with community-tuned precision, reducing drift for optimal performance.Compact and Versatile: Ideal for VR, wearables, and IoT with a small footprint and robust functionality.Unlock unparalleled motion tracking with Smol Slimes—small size, big performance!Please use the firmware named 'Chrysalis'.Package includes:1 x Smol Slimes V2.1 Tracker;1 xQuick-Release Buckle(1000mm)
