Pmod ACL2 │ 三軸MEMS加速度計模組 │ SPI

DIGILENT Pmod ACL2 是由 Analog Devices ADXL362 驅動的三軸 MEMS 加速度計模組。透過 SPI 與晶片通訊,每個加速度軸的解析度最高可達 12 位元。 此模組透過其運動激活的睡眠和喚醒模式,可提供自由落體檢測以及節能功能。

  • 內建三軸MEMS加速度計
  • 每個軸的解析度高達 12 位元
  • 可自選解析度
  • 動態 / 靜態監控
  • 100 Hz時僅有不到 2μA 的電流消耗
  • 自由落體檢測
  • 適用於各種設計的小型PCB (2.5cm*2.0cm)

Pmod ACL │ 三軸加速度計模組 │ I²C SPI

Pmod ACL 是一個三軸數位加速度計模組,可為主機板提供相應的輸入。用戶可透過 SPI 或 I2C介面與 Analog Devices ADXL345 通訊,指示 Pmod 的定向角度。

  • 3軸,±2/4/8/16g 加速度計
  • 可自選解析度
  • 活動/非活動監控
  • 單/雙擊與自由落體檢測
  • 適用於各種設計的小型PCB尺寸(2.5cm x 2.0cm)
  • SPI 介面與 2x4 pin I²C 介面的 12 pin Pmod連接器 

 

A data stream setting the threshold activity to a value of 250 mg and Interrupt 1 to be triggered whenever
the X and Y axis exceeds the threshold level through SPI is provided below:
