Description

MIKROE Accel 15 Click is a compact add-on board that contains a longevity acceleration sensor. This board features the BMA490L, a high-performance 16-bit digital triaxial acceleration sensor with extended availability of up to ten years from Bosch Sensortech. It allows selectable full-scale acceleration measurements in ranges of ±2g, ±4g, ±8g, and ±16g in three axes with a configurable host interface that supports both I2C and SPI serial communication and with intelligent on-chip motion-triggered interrupt features. Intelligent signal processing and evaluation in the accelerometer ASIC enables advanced gesture recognition for numerous industrial IoT applications where low power consumption is vital. This Click board™ is suitable for home appliances, power tools, and other industrial products whose lifetime is essential.

Accel 15 Click as its foundation uses the BMA490L, a high-performance 16-bit digital triaxial longevity acceleration sensor with extended availability of up to ten years from Bosch Sensortech. The BMA490L is highly configurable with a programmable acceleration range of ±2/±4/±8/±16g, and intelligent on-chip motion-triggered interrupt features (any/no motion) optimised for industrial applications, routed to the INT and AN pins of the mikroBUS™ socket. In addition to all these features, it also has excellent temperature stability (low-temperature drift), low noise, and low offset.

The sensor features a high-performance measurement mode with low pass filters and current consumption of 150μA in Full-Operation Mode, making it robust to temperature fluctuations with a maximum output data rate of 1.6 kHz. In Low-Power Mode, the current consumption is reduced to 14 µA, meeting the current-consumption requirements of Always-On applications.

Accel 15 Click provides the possibility of using both I2C and SPI interfaces with a maximum frequency of 1MHz for I2C and 10MHz for SPI communication. The selection can be made by positioning SMD jumpers labelled as COMM SEL to an appropriate position. Note that all the jumpers' positions must be on the same side, or else the Click board™ may become unresponsive. While the I2C interface is selected, the BMA490L allows the choice of the least significant bit (LSB) of its I2C peripheral address using the SMD jumper labelled as ADDR SEL.

This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
