MIKROE 3-Axis MEMs Accelerometer Click Boards

Shake2Wake click from Mikroelektronika carries an ADXL362 ultralow power, 3-axis MEMS accelerometer from Analog Devices. The distinguishing feature of this IC is that it incorporates several activity detection modes. The interrupt pins from the chip are connected to an onboard ADP195 power switch IC that in turn controls an external device connected through a screw terminal. The detection threshold is configurable (both intensity and duration). The duration of inactivity that leads to switching off is also programmable. Shake2Wake click can also be used as a regular accelerometer for continuous sensing in which case it communicates with the target MCU through mikroBUS SPI. It uses a 3.3 V power supply only.

Accel Click™ is an accessory board in mikroBUS form factor. It features the ADXL345 3-axis accelerometer module with ultra-low power and high resolution (13-bit) measurement. The module supports several sensing functions such as single/double tap detection, activity/inactivity monitoring, free-fall detection, etc. It has a memory management system with a 32-level FIFO buffer to store data with minimized host processor activity. The board is designed to use 3.3 V power supply only.
