Instruduction:Introducing Smol Slimes，also known as nRF Trackers, the next evolutions 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 TDKs’s cutting-edge ICM-45686 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.
