Plug-and-Play

Effortlessly connect ADXL345/S2DW to your Klippered printer with a simple setup, taking advantage of high-performance MCU hardware SPI for data sampling and communication, and enjoy compatibility with various host systems, easily connect to Raspberry Pi or Manta boards + CB1 with USB ports using a standard USB-A to USB-C cable.

Flexible Mounting Options

Method 1: StealthBurner Direct Mount

Method 2: Nozzle Mount

S2DW Remarkable Accuracy and Stability

The S2DW features the LIS2DW12TR, offering the same acceleration measurement capabilities as the adxl345. With higher sensitivity, lower noise, and improved temperature stability, the LIS2DW12TR achieves excellent precision and consistency.

Refer to this link for Klipper configuration

https://www.klipper3d.org/Measuring_Resonances.html.

The wiring in the link is directly connected to the Raspberry Pi. If you want to connect to the MCU motherboard, you can refer to the following wiring and configuration:

[adxl345]

cs_pin: PD9

spi_bus: spi1

#spi_software_sclk_pin: PA5

#spi_software_mosi_pin: PA7

#spi_software_miso_pin: PA6

1. The ADXL345BCCZ three-axis accelerometer needs to have a stable installation plane, otherwise it will affect its measurement accuracy.

2. Note that the board is powered by 5V, and 5V and GND cannot be reversely connected.
