Industrial Gateway

The RISC-V Industrial Gateway is an edge gateway product developed using LeapFive’s NB2L (LF555). It caters to various industrial edge computing scenarios, integrating numerous industrial interfaces and resources, including RS485, RS232, Ethernet, USB, CAN, DI/DO, HDMI, and TF card slots. The gateway also supports optional wireless communication modules such as Wi-Fi, Bluetooth, 4G/5G. On the software side, it runs the Linux operating system with middleware like Docker for easy application development and deployment.

New Power System: Source-Grid-Load-Storage Collaborative

The new power system source network load storage scheme takes NB2 series chip as the main control, adopts AI optimization control algorithm, integrates photovoltaic, wind power, hydropower and other distributed power supply and energy storage resources through a highly flexible platform, and realizes the comprehensive perception and coordinated control of source, load and storage. The system supports applications such as "peak and valley cutting, demand response, and power quality optimization" to meet diversified power needs and is suitable for scenarios such as distributed power management, grid intelligent regulation and energy system optimization.
