ADXL337 三軸加速度計模組 SparkFun 原裝進口

ADXL337 是一款小型,薄型,低功耗,完整的3軸加速度計,具有信號調節的模擬電壓輸出,可在±3g的滿量程範圍內測量加速度。該開發板已斷開從加速度計獲取必要數據所需的所有引腳。該突破非常適合磁盤驅動器保護,遊戲控制器和圖像穩定等應用。輕鬆進行ADXL337分組設置。只需為加速度計提供電源(3.3V和GND),然後將傳感器的X,Y和Z線連接到所選開發板上的ADC引腳即可。甚至可以選擇帶寬以適合所需的應用,X和Y軸的帶寬範圍為0.5 Hz至1600 Hz,Z軸的帶寬範圍為0.5 Hz至550 Hz。

應該注意的是,該 ADXL337 三軸加速度計模組 的最大電壓為3.6V。幸運的是,使加速度計正常工作不需要太多的電源。在正常工作模式下,它們通常消耗約300 µA的電流。

The ADXL337 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned analog voltage outputs that measures acceleration with a full-scale range of ±3g. This board has broken out all the pins you’ll need to get the necessary data from the accelerometers. The breakout is perfect for applications like, disk drive protection, game controllers, and image stabilization.

Getting the ADXL337 Breakout set-up is easy. Simply supply the accelerometer with power (3.3V and GND), then hookup the X, Y, and Z lines of the sensor to ADC pins on your chosen development board and you will be good to go. Bandwidths can even be selected to suit the needed application, with a range of 0.5 Hz to 1600 Hz for X and Y axes and a range of 0.5 Hz to 550 Hz for the Z axis.

It should be noted that this breakout has a maximum voltage of 3.6V. Fortunately, you won’t need a lot of power to make the accelerometers work. In normal operating mode they typically draw about 300 µA.


  • Operating Voltage: 1.8V – 3.6V
  • Typical Current: 300 μA
  • Range: ±3g
  • 3-axis sensing
  • Bandwidth adjustment with a single capacitor per axis
  • 1x Mounting Hole
