[0028] The utility model embodiment provides a universal development board; Figure 1 A schematic diagram of the working modules of an embodiment of a universal development board provided by the utility model; Figure 1 As shown, the universal development board includes a core board 10, a fixed function board 20 and a non-fixed function board 30;
[0029] The core board 10 is connected to the fixed function board 20, and the fixed function board 20 is connected to the non-fixed function board 30;
[0030] The fixed function board 20 is used to lead out the function pins of the core board 10 and realize the fixed function;
[0031] The non-fixed function board 30 is used to expand variable functions based on the fixed function board 20 .
[0032] It should be noted that in the embodiment of the utility model, the general development board is generally composed of a core board 10 and a base board. The utility model divides the base board into two base boards, a fixed function board 20 and a non-fixed function board 30. Among them, the core board 10 generally includes five main functional modules: CPU (Central Processing Unit), power management, memory, storage and field bus. It has a very high degree of integration and can realize various functional development requirements. The real realization of the function requires the coordinated development of the base board and external devices. The fixed function board 20 leads out all the functional pins of the core board 10 and designs fixed functions such as power supply, burning, USB (Universal Serial Bus) on the fixed function board 20. These fixed functions are basic operating functions, have universality, and will not be easily changed. The non-fixed function board 30 realizes function expansion, and the developer performs variable function expansion on other function pins led out from the fixed function board 20 according to actual development needs, which saves the developer's design time for basic fixed functions, enhances the versatility of the development board, and retains the possibility of functional expansion of the development board.
[0033] Compared with the prior art, the universal development board provided by the utility model includes a core board 10, a fixed function board 20 and a non-fixed function board 30; the core board 10 is connected to the fixed function board 20, and the fixed function board 20 is connected to the non-fixed function board 30; the utility model leads out all the function pins of the core board 10 through the fixed function board 20 and realizes basic universal fixed functions based on some of the led-out function pins, and then uses the non-fixed function board 30 to lead out other function pins on the fixed function board 20 except for the function pins related to the basic functions, and expands variable functions based on the other led-out function pins, adapts to actual needs, improves the versatility of the development board, and makes it unnecessary for staff to design basic functions during development, and only needs to expand functions on the non-fixed function board 30 according to actual needs, which greatly saves development time and cost.
[0034] In some embodiments of the present invention, the function pins include fixed function pins and non-fixed function pins.
[0035] It can be understood that in the embodiment of the utility model, the core board 10 has a large number of function pins. The function pins are distinguished according to the functional universality, and the pins corresponding to the functions are fixed function pins, and other function pins except the universal function pins are divided into non-fixed function pins. All the function pins are first led out through the fixed function board 20 and the universal fixed functions are realized based on the fixed function pins, and then the non-fixed function pins are led out from the fixed function board 20 through the non-fixed function board 30 to realize variable function expansion, that is, the realization of non-fixed functions.
[0036] In some embodiments of the present invention, the fixed function board 20 is connected to the core board 10 by using a main connector 40 .
[0037] It can be understood that in the embodiment of the utility model, the main connector 40 can be a connector in the form of a gold finger plug-in, or a connector composed of a wiring harness. The utility model does not limit this. The number of pins of the main connector 40 is determined by the number of functional pins of the core board 10. In the specific implementation, since the core board 10 is designed based on the T507 chip, a corresponding 260-pin main connector 40 is used.
[0038] In some embodiments of the present invention, the fixed function board 20 includes a power supply module 210 and a fixed function module 220;
[0039] The power supply module 210 is used to provide power to the core board 10, the fixed function board 20 and the non-fixed function board 30;
[0040] The fixed function module 220 is used to lead out the fixed function pins of the core board 10 and implement the fixed functions.
[0041] It can be understood that in the embodiment of the utility model, the power supply function is the basis for the operation of the development board and is the most basic function that each development board should have, while the fixed function module 220 is a module that can realize functions such as reset, burning, video recording, data transmission, etc., which are relatively common functions and are realized through development by the fixed function board 20 based on the fixed function pins led out.
[0042] Reference Figure 2 , Figure 2 A structural schematic diagram of an embodiment of a universal development board provided by the utility model; Figure 2 SW1 is the reset port, SW2 is the programming port, CON1 is the USB port, J4 is the camera connection port, and J5 is the HDMI interface. Figure 2 It can be seen that the core board 10 is arranged above the fixed function board 20 and is connected through the main connector 40. The main connector 40 and the branch connector 50 are both arranged on the fixed function board 20. The connection between the fixed function board 20 and the non-fixed function board 30 can be achieved by simply inserting the interface of the non-fixed function board 30 into the branch connector 50. In some embodiments of the present invention, the fixed function module 220 includes a reset unit 221, a burning unit 222, a USB unit 223, a camera unit 224 and an HDMI (High Definition Multimedia Interface) unit 225.
[0043] It can be understood that in the embodiment of the utility model, the development board can be reset through the reset unit 221, the program can be burned through the burning unit 222, the USB unit 223 provides a USB interface for developers to transmit data, the camera unit 224 provides a port for camera connection to facilitate the installation of a camera, and the HDMI unit 225 provides a high-definition multimedia interface to realize audio and video data transmission.
[0044] In some embodiments of the present invention, the fixed function board 20 is connected to the non-fixed function board 30 via a branch connector 50 .
[0045] It can be understood that in the embodiment of the utility model, since the fixed function board 20 leads out all the functional pins of the core board 10 through the main connector 40 and realizes some fixed functions, the non-fixed function board 30 leads out the remaining unrealized functional pins (i.e., non-fixed functional pins) from the fixed function board 20 through the branch connector 50 to facilitate variable functional expansion. The branch connector 50 is implemented in a similar manner to the above-mentioned main connector 40, except that the number of pins is less than that of the main connector 40. In specific implementation, a 140-pin connector can be used.
[0046] In some embodiments of the present invention, the non-fixed function board 30 is used to lead out non-fixed function pins based on the branch connector 50 and the main connector 40 and to extend variable functions through the non-fixed function pins.
[0047] It can be understood that in the embodiment of the utility model, the non-fixed function pins are first led out to the fixed function board 20 through the main connector 40, and then the non-fixed function pins are led out to the non-fixed function board 30 through the branch connector 50, so that developers can perform variable function expansion, and the power supply module of the fixed function board 20 can provide power and other basic general functions to the non-fixed function board 30. Developers only need to design the extended functions without designing the corresponding supporting basic functions.
[0048] In some embodiments of the present invention, the variable functions include a panel display function, a network port function, and a peripheral integration function.
[0049] It is understandable that in the embodiments of the present invention, the variable functions are not limited and may be a separate video display function, a network port function, other peripheral functions, or may integrate multiple functions mentioned above, which are not listed one by one in the present invention.
[0050] In some embodiments of the present invention, the core board 10 includes a T507 chip.
[0051] It can be understood that in the embodiment of the utility model, the core board 10 is a core development board designed based on the T507 chip. The CPU of the core development board adopts the domestic industrial-grade chip T507, a quad-core Cortex-A53 processor, and an internally integrated GPU (graphics pr ocessing unit) of model G31MP2. It supports multiple display interfaces and dual-screen displays, with a maximum resolution of up to 4K. The core board 10 integrates DDR4 (Double Data Rate Fourth Generation Synchronous Dynamic Random Access Memory), EMMC (Embedded Multi Media Card, universal flash storage), power management chips and other core components, which reduces the development complexity of users.
[0052] The utility model also provides a universal development platform, which includes the universal development board mentioned above. The specific embodiment of the universal development platform refers to the embodiment of the universal development board mentioned above, and will not be described in detail here.
[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
