A utilitarian tracker design for SlimeVR, with the intention of using the cheapest parts available in the smallest form factor possible, while maintaining quality and usability.
NEW! Revision 2 motherboards have been added, removing the BMI160-QMC5883 IMU-Magnetometer combo, and replacing it with an LSM6DSR board which has a magnetometer built in. Technically, the LSM6DSR board is pin-compatible with the BMI160 (and therefore is compatible with the old rev 1…
