ACCEL CLICK MikroElektronika

2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 Accel click 2 3 1. Introduction 4. Essential features Accel Click with its ADXL345 module supports several sensing functions such as single/double tap detection, activity/inactivity monitoring, free-fall detection etc. It has memory management system with a 32-level Turn the board upside down so that Turn the board upward again. Make sure FIFO buffer to store data with minimized host bottom side is facing you upwards. Place to align the headers so that they are processor activity. All these features make shorter parts of the header pins in both perpendicular to the board, then solder the this board ideal for mobile devices, medical soldering pad locations. pins carefully. and industrial instrumentation, navigation devices, hard drive protection and more. Accel Click is an accessory board in mikroBUS form factor. Its a compact 3. Plugging the board in and easy solution for adding accelerometer click functionality to your device. It features Once you have soldered the headers your ADXL345 3-axis accelerometer module with board is ready to be placed into desired BOARD ultra-low power and high resolution (13-bit) mikroBUS socket. Make sure to align the www.mikroe.com measurement. Accel Click communicates cut in the lower-right part of the board with 2 with target board via I C or SPI interface. The the markings on the silkscreen at the Accel click Manual Board is designed to use 3.3V power supply mikroBUS socket. If all of the pins ver. 1.00 only.

Accel Click Board Schematic The Accel Click board communicates 2 with the main board via I C or SPI interface depending on the position of the J1, J2 and J3 SMD jumpers. These jumpers are soldered in 2 I C interface position by default. There is an option to select the alternate address with 2 jumper J4 in the case of I C interface (default position is logic 1).
