Recently, Hunan Kaihong Zhigu Digital Industry Development Co., Ltd. (referred to as "Kaihong Zhigu"), a subsidiary of Tuowei Information, launched the Niobe 407 development board based on the STM32F407IGT6 chip and officially incorporated it into the backbone of the OpenAtom OpenHarmony (referred to as "OpenHarmony") community. As a development board for industry, transportation and other fields, Niobe 407 has high performance, high stability, multi-function and other highlights, and meets the needs of industrial-grade components.
The STM32F407IGT6 chip is a highly integrated and high-performance MCU built by STMicroelectronics. It is equipped with an ARM® Cortex™-M4 32-bit core with a working frequency of up to 168 MHz, and has a floating-point unit FPU (this unit supports all ARM units. precision data processing instructions and data types), and has Ethernet MAC10/100 that complies with IEEE 1588 v2 standard requirements and supports wired Ethernet.
As an OpenHarmony ecological co-construction unit, Kaihong Zhigu Company actively promotes the OpenHarmony chip adaptation process, breaks through and completes the adaptation of the STM32 F407IGT6 chip to OpenHarmony 3.1 Release, and launches the OpenHarmony development board based on this chip - Niobe 407, and has successively promoted This development board has passed OpenHarmony 3.1 Release version and OpenHarmony master compatibility evaluation.
The Niobe 407 development board adopts a double-board stacked structure with rich peripheral resources and powerful and efficient functions: the upper and lower layers are the core board (Core) and the base board (Base). The core board integrates high-speed embedded memory, with 1MB of Flash and 192KB of SRAM, leading out in the form of "four-sided stamp holes"; the bottom board includes RJ45 Ethernet, CAN, RS232, R485, I2C, full-speed USB OTG, power input, LED, buttons , general-purpose input and output, Micro SD, Nand SIM and other interfaces, as well as optional functional modules such as 4G, Wi-Fi/BLE and Lora. Developers can use the Niobe407 development board for experimental development, rapid verification and development of corresponding software functions, and at the same time use the core board for intelligent hardware development, which greatly shortens the product development cycle and accelerates the marketization of intelligent products.
The STM32F407IGT6 chip with rich peripheral resources and powerful performance has attracted much attention inside and outside the industry, and has been used by thousands of industries before. The launch of the Niobe 407 development board this time promotes the integration of the STM32F407IGT6 chip into the OpenHarmony ecosystem, which not only expands the diversification of the OpenHarmony chip platform, but also lowers the entry threshold for OpenHarmony devices, injecting new momentum into accelerating the process of OpenHarmony "lighting up" billion-level industry devices .
