Product Details
The MIKROE Accel 15 Click is a super - compact add - on board housing a long - lasting acceleration sensor. It's powered by the BMA490L from Bosch Sensortech, a high - performance 16 - bit digital triaxial acceleration sensor available for up to ten years. With selectable full - scale acceleration measurements from ±2g to ±16g across three axes, it features a configurable host interface supporting both I2C and SPI serial communication, along with smart on - chip motion - triggered interrupts. The intelligent signal processing in the accelerometer ASIC enables advanced gesture recognition for low - power industrial IoT applications. This Click board is ideal for home appliances, power tools, and other long - lifespan industrial products. The BMA490L offers high configurability with a programmable acceleration range and optimized motion - triggered interrupts. It has great temperature stability, low noise, and low offset. In full - operation mode, it consumes 150μA with a max output data rate of 1.6 kHz, and in low - power mode, it drops to 14 µA, perfect for always - on apps. You can choose between I2C and SPI interfaces, with max frequencies of 1MHz for I2C and 10MHz for SPI. Select the interface by positioning the COMM SEL SMD jumpers, and make sure they're all on the same side. When using the I2C interface, you can choose the LSB of the I2C peripheral address via the ADDR SEL SMD jumper. This Click board runs on a 3.3V logic voltage level. If using with MCUs of different logic levels, do proper voltage conversion. It comes with a library having functions and example code for further development. Features include I2C and SPI interfaces, mikroBUS™ compatibility, 28.6 x 25.4mm dimensions, 3.3V input voltage, an acceleration range from ±2g to ±16g, sensitivity from 16384 LSB/g to 2048 LSB/g, bandwidth from 0.75Hz to 800Hz, output data rate from 12.5Hz to 1600Hz, and an operating temperature range from - 40°C to +85°C. Available documents are the schematic, BMA490L datasheet, mikroSDK, and GitHub.
Using the MIKROE Accel 15 Click is straightforward. First, connect it to your device using either the I2C or SPI interface. To select the interface, position the COMM SEL SMD jumpers. Make sure all jumpers are on the same side; otherwise, the board might not work. When using the I2C interface, you can also choose the least significant bit of the I2C peripheral address with the ADDR SEL SMD jumper. This board runs on a 3.3V logic voltage level. If your MCU has a different logic level, you need to do a proper voltage - level conversion before use. The board comes with a library that has functions and example code. You can use these as a reference to develop your own applications. As for maintenance, keep it in a clean and dry environment. Avoid exposing it to extreme temperatures outside the operating range of - 40°C to +85°C. If you're not using it for a long time, store it properly to prevent any damage. Also, when handling the board, be gentle to avoid any physical damage to the components.
