Supports Bluetooth for point-to-point full-duplex communication, and the measured straight-line communication distance can reach 50m+.
The overall low-power design is implemented. The LDO voltage stabilizing part uses the ultra-low IQ Texas Instruments TPS782; the Bluetooth module uses Qinheng's low-power Bluetooth solution; the vibration motor uses a Japanese-made SMD low-power vibration motor.
Powered by a 110mAh lithium battery, the battery life can reach 8h+. Use the TYPE-C interface to charge the device and indicate the charging status through LED. It also has overcharge/over-discharge protection function and low battery monitoring circuit. The system supports use while charging.
The main control uses 16pin STC15W204S.
