Accel 3 click carries the H3LIS331DL a low-power high-performance 3-axis linear accelerometer. The click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over SPI or I2C interface, with additional functionality provided by the INT pin on the mikroBUS™ line.
The H3LIS331DL has dynamically user selectable full scales of ±100g/±200g/±400g and it is capable of measuring accelerations with output data rates from 0.5 Hz to 1 kHz.
The “sleep-to-wakeup” function, in conjunction with low-power mode, allows to further reduce the system power consumption and develop new smart applications.
The H3LIS331DL may be set in a low-power operating mode, characterized by lower date rate refreshments. In this way the device, even if sleeping, continues to sense acceleration and generate interrupt requests.
When the “sleep-to-wakeup” function is activated, the H3LIS331DL is able to automatically wake up as soon as the interrupt event has been detected, increasing the output data rate and bandwidth.
Accel 3 click has three groups of jumpers (zero ohm resistors) onboard:
