LIS2DH taking more than 100 uA

We are using LIS2DH in our board for production. Among 1000 boards, about 50 boards were drawing much more power because of LIS2DH (the IC is functional - we are getting the accelerometer data). Once we remove the IC from the board, current dropped f...

Need soldering temperature profile for LIS2DE12

Hi, I am mounting the LIS2DE12 IC's using Infrared IC reflow machine using the profile having 257 °C peak. IC got soldered but, it is not detected, when I tried to communicate with it. I have tried for 3 IC's with same resulted. I suspect the t...

Dear Sir, How to connect Sensor tile cradle expansion board to PC and I tried with ST youtube video. But I unable to connect. My second question is I want to save the sensor tile Acceleration and Gyroscope data to the sd card. I requerst you suggest me

I want a 1000 data per seconds from LSM6DSM sensor (Acceleration and Gyroscope data ) and I want set acceleration level should +16g to -16g and gyroscope value should be 2000dps. These data should saved to the sd card. I request you to kindly sugges...

Problems calibrating VL53L0X ToF distance sensor (VL53L0X_perform_offset_calibration, VL53L0X_perform_xtalk_calibration). bug?

RoutineVL53L0X_perform_offset_calibration from src/core/src/vl53l0x_api_calibration.cpp is giving strange results. By my opinion the problem is in uint16_t sum_ranging which should be of type uint32_t due to later bit shifting (<<16), which needs to ...

Bandwidth vs ODR

Hi,I would like to know what is the difference between bandwidth and ODR. I tough that just the analog accelerometers have bandwidth and the digital ones have ODR. For example, IIS3DWB can go up to 5kHz bandwidth and 26.7kHz ODR. Does this means that...
