The new DEMOSTBMPL3115A2 Evaluation Board provides integrated capabilities for both low power applications and advanced sensing needs. This board is especially designed for applications that need low power and low noise operation, such as medical sensing, industrial, automotive, building automation, IoT and wearables. Additionally, it is a flexible solution that is suitable for prototyping and fast evaluation without the need to host extra computing power for firmware.

Introduction

The DEMOSTBMPL3115A2 Evaluation Board is an easy-to-use, low-power evaluation board with integrated sensors and data processing functions. It contains two main elements, the processor and the sensing elements. It is designed to provide a complete solution with low power consumption and low noise operation. The DEMOSTBMPL3115A2 Evaluation Board integrates a 6-axis (3-axis gyroscope + 3-axis accelerometer) motion tracking unit, which can operate correctly or in low-power data acquisition mode. This motion tracking function is combined with a pressure sensor of 0-30An Hg range. The sensing elements are supported by a low power Cortex-M0 processor with high speed interfaces. In addition, the board also contains a number of I/Os including a debug port, a reset pin, SPI flash and multiple LEDs.

Application Fields

Due to its low power operation, the DEMOSTBMPL3115A2 Evaluation Board can be used in many different applications. It can be used in medical sensing, industrial applications, automotive, home automation, Internet of Things (IoT) and wearable devices. Some of the more popular applications include 3D motion tracking, such as robotic navigation, odometry, and inertial navigation; and pressure sensing, such as pressure monitoring for medical and industrial applications.

Working Principle

The DEMOSTBMPL3115A2 Evaluation Board consists of a number of components that work together to control and operate the board. The main component is the processor, which communicates and interfaces with the other components including the sensors. In low-power data acquisition mode, the processor will draw a very small amount of power, typically just a few mA. The processor will then use the data acquired from the sensors to determine the current position, pressure, temperature, etc. and the relevant output will be generated. The other components will also interact with the processor to provide additional inputs, such as buttons or switches, to the system, or outputs, such as LED indicators.

The pressure sensor is also interfaced with the processor. It utilizes a 32-bit ADC to measure pressure, temperature, and light intensity. The data acquired from the pressure sensor is transmitted to the processor where it is processed and the relevant output is generated. The motion tracking unit is integrated with a 6-axis inertial measurement unit (IMU) consisting of 3-axis accelerometers and 3-axis gyroscopes. This unit interfaces with the processor and communicates with the sensors, and provides a 3D motion tracking solution.

The user can also access the data from the processors embedded memory. The processor also has the capability to write data directly to its own memory or to external nonvolatile memory, such as flash memory.

Conclusion

The DEMOSTBMPL3115A2 Evaluation Board is an all-in-one solution for sensor data acquisition, motion tracking and low power consumption. This board provides a flexible and fast solution for prototyping and testing applications where low power and low noise is required. The board integrates a processor, IMU, pressure sensor, and various I/O connections, providing an ideal solution for medical and industrial applications.
