Boards in 2 GitHub repositories, designed in KiCad, that use the ISM330IS by STMicroelectronics (-40℃~+85℃ 1.71V~3.6V 16bit 6uA IMU (accelerometer + gyroscope) SPI、I2C X,Y,Z X,Y,Z ±16g ±2000dps VFLGA-14L(2.5x3) Accelerometers ROHS). See how each wires it, with its parts, size, README and files; the ISM330IS’s symbol, footprint and pinout are on its own page.
