accelerometers which can be used to measure resonance frequencies of the printer

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>
