The SOM330 series is a fully domestic industrial core board based on the Allwinner Technology T113-i heterogeneous multi-core processor, featuring a dual-core ARM Cortex-A7, Xuartie C906 RISC-V, and HiFi4 DSP. The ARM Cortex-A7 processing unit operates at up to 1.2 GHz. All components, including the CPU, ROM, RAM, power supply, and crystal oscillator, are domestically produced industrial-grade solutions, achieving a 100% localization rate.
The core board uses stamp-hole connections to provide interfaces such as CAN, UART, SPI, TWI (I2C), EMAC, USB, LVDS DISPLAY, RGB DISPLAY, MIPI DSI, CVBS IN/OUT, and CSI. It supports hardware video encoding for 1080P@60fps JPEG/MJPEG and hardware decoding for 4K@30fps H.265 and 4K@24fps H.264. The board has undergone professional PCB layout and high/low-temperature testing, ensuring stable and reliable quality to meet various industrial application requirements.
The SOM330 series supports operating systems such as Linux-4.9.170, Linux-RT-4.9.170, and Ubuntu 20.04, along with development tools like Docker containers, Node-Red, and Qt-5.12.5 for graphical interface development.
The SOM330 series is designed for reliability and stability through professional electrical performance design and high/low-temperature testing, making it suitable for diverse industrial applications, including industrial IoT, edge computing gateways, photovoltaic power generation and storage systems, automation control, and railway transportation.
