Description
Description
SlimeVR tracker using nRF52840 mcu focusing on high efficiency and power management
Supports most IMU (inertial measurement unit), along with MMC5983MA. Use at least 100mAh battery
Firmware: https://github.com/SlimeVR/SlimeVR-Tracker-nRF
- Effective power mangagement from nRF52
- Switching between LDO and DCDC for lowest quiescent current and better efficiency at high current
- Diode power path while charging
- Enable pin for oscillator
- All sensors can be powered down from I2C
