SlimeVR Butterfly Trackers – nRF52833-based, ultra-slim, full-body VR trackers offer up to 48h battery life (Crowdfunding)

Designed by SlimeVR in Rotterdam, Netherlands, the SlimeVR Butterfly Trackers are open-hardware, IMU-based, ultra-slim, full-body VR trackers designed for virtual reality gaming, motion capture, VTubing, and more. The trackers provide full-body positional tracking without base stations, cameras, Wi-Fi, or Bluetooth. Each tracker uses an IMU to measure absolute rotation and transmits data over a custom 2.4 GHz ESB protocol via a dedicated dongle supporting up to 10 trackers, eliminating occlusion issues and router setup. Based on Nordic Semi’s nRF52833 wireless MCU, the split “butterfly” design places the PCB and 90 mAh battery side-by-side to achieve a thickness of under 7 mm and a weight below 10 grams, while a flexible interconnect improves comfort when worn under clothing. The system offers a 100–200 Hz refresh rate, <15 ms latency, over 48 hours of battery life with USB-C charging and OTA firmware updates.
