The Loongson 1C open-source motherboard is a groundbreaking development in the world of domestic hardware innovation. While open-source software has been widely adopted, open-source hardware remains relatively rare—especially in China. The Loongson Club and Guangzhou Loongson have taken a significant step forward by successfully debugging the Loongson 1C, an open-source motherboard that can boot up the Linux system effectively.
This compact motherboard, similar in size to a Raspberry Pi, integrates the Loongson 1C SOC processor along with essential components like the RTC clock. It offers a wide range of expansion interfaces, including RJ-45, USB, serial ports (up to 12 channels), SPI, PWM, CAN, and an SD card slot. This makes it ideal for running embedded Linux systems and enabling various network applications.
The Loongson 1C is based on the LS232 IP core and is designed for versatile embedded applications. It comes in a QFP package with exposed pins, allowing hardware engineers to solder it manually without the need for automated equipment. For those requiring more connectivity options, an expansion board with dual-row connectors can be used, supporting modules like Arduino, Microduino, and XBee.
Wireless capabilities include Bluetooth, Zigbee, Wi-Fi, GPS, Beidou, GPRS, and NFC, making it suitable for smart home gateways, 3D printers, webcams, and digital photo frames. The open-source nature of the Loongson motherboard allows for full customization, as both the PCB design and software code are freely available for use and redistribution.
Currently, the project has partnered with Fupu 3D, a domestic 3D printing team, to develop a Loongson-based 3D printer solution. It also collaborates with IoT platforms to enable remote data acquisition and control through automatic access to the IoT data center.
In 2015, the Loongson Club plans to launch several open-source hardware demonstration projects using the Loongson 1C, showcasing its potential in areas such as wireless home gateways, industrial control systems, and human-machine interfaces like digital photo frames.
With its low cost and flexibility, the Loongson 1C is an excellent choice for makers, students, educators, and startups looking to develop intelligent hardware prototypes. Its open-source model promotes innovation and accessibility, making it a powerful tool in the growing field of embedded systems and the Internet of Things.
