“Open Source Godson Motherboard” is a Godson embedded motherboard developed by Godson Club and Godson in an open source way. It integrates Godson 1CSOC, network port, USB port, power supply, SD card slot, RTC clock and other main components on a small circuit board with the same specifications as “Raspberry Pi”. It can run embedded Linux system and complete various applications. PCB specifications guarantee the size of a postcard. The hardware configuration and software development of the Loongson motherboard are completely open-source, completely free of charge, and everyone can apply it at will. The first collection edition specially promotes the laser marking area of personalized commemorative texts, and customers can customize the laser marking content, such as name, nickname, date, signature, etc., which is convenient for commemorative collection.
Loongson 1CSOC chip is a cost-effective single-chip system based on LS232CPU core. It has a variety of external device sockets and upper control modules, showing developers sufficient measuring ability and multi-application connection ability. It can be used in the fields of fingerprint identification, biometric identification technology and Internet of Things sensing technology.
Loongson 1C
This motherboard is mainly for Loongson enthusiasts, students, makers and embedded developers, and can be widely used in the fields of network communication, Internet of Things, intelligent control and embedded teaching, especially in today’s popular intelligent hardware development.
It is reported that “Open Source Loongson Motherboard” has the following characteristics compared with other open source motherboards:
The sockets are rich and colorful, and 12 serial communication channels can be reused. In the application of the Internet of Things, more serial communication data information and serial communication sensor communication requirements can be considered. In addition, the integrated network port can complete the technology of connecting multi-channel serial communication machines and equipment to the Internet. And the Loongson 1C chip is low in price, high in cost performance, and suitable for industrial popularization.
The motherboard can be completely hand-made by electric welding. From the perspective of embedded teaching and rapid hardware design, Loongson 1C chips are packaged in QFP, and the pins of the chips are exposed for independent electric welding by electronic engineers. Nowadays, some open source motherboard chips usually use BGA packages with hidden pins. Although the features are good, the equipment must be welded. If the cycle time of hardware configuration iterative update is short, the cost of equipment patch will be greatly increased, and “Open Source Loongson Motherboard” only needs a skilled welder to weld all electronic devices in one night.
The local manufacturer is applicable and the chip can be customized. The Loongson chip SMT patch and PCB copy board are simple. In the long run, the field of intelligent hardware will also encounter all kinds of customized chips and licensing fees like intelligent machines. Loongson chip is an independent CPU core, and its ability to customize chip design scheme is strong, and its licensing fee is low. It seems that it is a very, very good choice from the application of design scheme to SMT chip production cost.
