ADXL362 evaluation board EVAL-ADXL362Z

The EVAL-ADXL362Z is a simple breakout board that enables easy connection of an ADXL362 micropower, 3-axis, digital-output MEMS accelerometer into an existing system. Due to its small size, the EVAL-ADXL362Z has minimal effect on performance of the system and of the accelerometer, and thus it is ideal for evaluation of the ADXL362 in an existing system. Note that the ADXL362 must be communicated with digitally via SPI. No processor is included with the EVAL-ADXL362Z; firmware must be supplied externally by the user. Some sample firmware is available at the link below:

The EVAL-ADXL362Z-MLP is a complete system for real-time evaluation of the ADXL362 micropower, 3-axis, digital-ouptut MEMS accelerometer. This system is accompanied by a graphical user interface (GUI) that facilitates evaluation of parameters such as power consumption, temperature coefficient, noise, and more. The system consists of a motherboard and a satellite board. The sensor is housed in a socket on the satellite board, enabling evaluation of multiple parts using one evaluation system.

To order the complete system, order the EVAL-ADXL362Z-MLP. This kit includes a motherboard, satellite board, accelerometer, and cables. Additional satellite board kits can be ordered using the part number EVAL-ADXL362Z-S. Satellite kit orders include a satellite board and an accelerometer.
