Hi ashnichloe67, Thank for your inquiry. According your description, is my understanding correct: Did you use sensors in the project? Do you want to review the sensor in the design? ... View more

Hi ewei, Thank for your inquiry. You can refer to the OIS diagram in BMI270 data sheet. The OIS controller obtains sensor data through SPI without the need for additional hardware interfaces. Typically, data synchronization between IMU and camera sensors is achieved by the OIS controller. ... View more

Hi DalesLandnet , Thank for your inquiry. BMA456 also supports any motion and double tap features in low-power mode without the need to reload firmware. When any motion or double tap events occur, the sensor will report an interrupt signal to the host to wake it up. Then the host read the interrupt status register of BMA456 to check which type of interrupt trigger (any motion, double tap, etc.) it is. ... View more

Hi ashareef, Thank for your inquiry. The recommended capacitor in the data sheet has already reached EOL. You can choose other capacitors. Here are some explanations about the factors to consider when choosing a capacitor: Capacitance value: greater than or equal to 2.2uF Capacitor size: The capacitor size is small, and the DC bias decays quickly. It is recommended to choose capacitors with a size of 0805. If a small-sized capacitor is chosen, the capacitance value needs to be increased. DC bias: For example, when powered by 3.3V, if the vertical axis capacitance deviation rate reaches 10%, the capacitance value decreases, affecting the charging and discharging of the capacitor, and thus affecting the voltage required by the sensor. When selecting a capacitor, it is necessary to check whether the new DC bias is better than the DC bias of the reference capacitor. If the DC bias is similar or better, it can be used. Inductance and ESR parameters: Select capacitors with parameters similar to those in the data sheet. ... View more
