Software open source is very common, but have you seen hardware open source? There are also domestic ones. It is understood that after the development of three versions of the Loongson Club and Guangzhou Loongson, the Loongson 1C open source motherboard has been successfully debugged, and the Linux system can be successfully started.
The open source Loongson motherboard is a Loongson embedded motherboard promoted by open source. It integrates Loongson 1C SOC processor, RTC clock, etc. on a small circuit board (matchbox size) of the same size as the Raspberry Pi. The main components, as well as RJ-45, USB, serial (up to 12 channels), SPI, PWM, CAN, SD card and other expansion interfaces, can run embedded Linux system to achieve network applications.
The Loongson 1C is a single-chip system based on the LS232 IP core. It is suitable for a variety of embedded applications. It is also available in a QFP package with exposed pins. Hardware engineers can solder by hand without machine patch.
If more interfaces are needed, it can also be exported through a dual-row plug-in expansion board, including expansion modules such as Arduino, Microduino, and XBee.
Wireless network supports Bluetooth, Zigbee, Wi-Fi, GPS, Beidou, GPRS, NFC, etc. It can be used in smart home wireless gateways, 3D network printers, web cameras, network digital photo frames, etc.
The open source Loongson motherboard is mainly for Loongson enthusiasts, students, makers, and embedded developers. It can be used in network communication, Internet of Things, intelligent control, and embedded teaching.
Compared with the existing Raspberry Pi and Arduino, the Loongson Open Source motherboard has lower overall cost in implementing functions such as webcam, access to the Internet, and wireless gateway. It is conducive to popularization, suitable for makers and educational teaching, and can also be used as intelligent hardware. Prototype development board for the startup team.
Because it is open source, there is no restriction on the design of the motherboard. The PCB design and software code will be open and unreserved. Any individual or organization can use it and redistribute it.
At present, the open source Loongson motherboard project has cooperated with the domestic open source hardware 3D printing team, Fupu 3D, to promote the Loongson 3D printer solution using the open source Loongson motherboard, and also cooperate with the domestic IoT platform to automatically access the IoT data center. Realize functions such as remote data acquisition and remote control.
The Loongson Club will also launch several open source hardware demonstration projects based on the open source Loongson motherboard in 2015 to demonstrate the capabilities of Loongson 1C, such as Loongson Wireless Home Gateway for Network, Loongson 3D Printer for Industrial Control, and Loongson Digital for Human Machines Photo frames and more.
