SEN0121 has a wealth of integrated components and functions. It supports various external devices to ensure that users can quickly and conveniently understand product functions and characteristics. Furthermore, it can be used to develop smart healthcare devices, automotive field, and so on.

Working Principle

SEN0121 is based on big.little processor with AI acceleration and embedded operating system, which can support real-time stream decoding and low power consumption mode. Meanwhile, it has a wide range of internal board peripherals such as 32-bit CAN, UART and SPI controllers to make a good integration of peripheral components. These components interact with the main board by collecting sensor information and controlling peripheral components to achieve the functions of the product.

The SEN0121 main board is connected to the main board via several small board interconnects called daughter boards, which provides a greater degree of scalability and compatibility. The daughter boards provide the communication with most of the external peripherals, such as Various GNSSs, NFC, Bluetooth and Wi-Fi modules, as well as power amplifiers and audio circuits for connection of external devices. The daughter boards also provide control logic for other preset functions like battery, DC-DC converter, and external interfaces like HDMI and UART.

The daughter boards leverage the board system by transmitting data through a network of serial links, which are used to communicate between all daughter boards and the main board.The SEN0121 main board is also integrated with external modules and components. These modules and components interface with the main board via either the I/O pins or via an I2C/SPI/UART connection, allowing data to be passed back and forth between the main board and the various modules and components. The data is then processed and used to control various components and peripherals on the board, as well as the hardware peripherals and external interfaces.

In addition, SEN0121 supports debugging with visual programming tools. This allows users to develop C, C++, JavaScript, and Python applications.It also supports the debugging and programming of multiple operating systems including FreeRTOS, Android, Linux, and Windows. This enables users to quickly develop and apply applications for their R&D projects.

To sum up, SEN0121 is a comprehensive evaluation board that offers a wealth of integrated components and functions, allowing users to quickly and conveniently understand product functions and characteristics, as well as easily achieving the desired application effect. It is suitable for the research and development of 5G or IoT solutions, as well as handheld multi-functional terminal devices, industrial control, scientific experiments, smart healthcare, and automotive field.
