<p>Klipper has built-in support for the ADXL345 and MPU-9250 compatible accelerometers which can be used to measure resonance frequencies of the printer for different axes, and auto-tune <a href="Resonance_Compensation.html">input shapers</a> to compensate for resonances. Note that using accelerometers requires some soldering and crimping. The ADXL345 can be connected to the SPI interface of a Raspberry Pi or MCU board (it needs to be reasonably fast). The MPU family can be connected to the I2C interface of a Raspberry Pi directly, or to an I2C interface of an MCU board that supports 400kbit/s <em>fast mode</em> in Klipper.</p>

<p>When sourcing accelerometers, be aware that there are a variety of different PCB board designs and different clones of them. If it is going to be connected to a 5V printer MCU ensure it has a voltage regulator and level shifters.</p>
<p>For ADXL345s, make sure that the board supports SPI mode (a small number of boards appear to be hard-configured for I2C by pulling SDO to GND).</p>

<p>For MPU-9250/MPU-9255/MPU-6515/MPU-6050/MPU-6500s there are also a variety of board designs and clones with different I2C pull-up resistors which will need supplementing.</p>
