● SBC880 Product Introduction
SBC880 is a configurable industrial control system that allows users to customize various functional modules according to their needs, facilitating the construction of hardware prototypes for the entire product. By developing application programs, the product can quickly enter the application market.
The SBC880 application motherboard is actually a complete single board industrial control computer, which can be equipped with various industrial control motherboards that comply with the ESMARC standard of Innolux, and can also support one SFP fiber interface. The SBC880 single board industrial control computer motherboard supports industrial control interface driver circuit modules that comply with the DM5028 specification, and also extends the DM5028 dedicated connection terminal to 28 bits, thereby achieving flexible configuration of driver interfaces. In addition, the SBC880 single board industrial control computer motherboard is also equipped with a mini PCI-e socket, which supports multiple 4G/GPRS/WiFi wireless communication modules.
The SBC880 single board industrial control computer motherboard provides the following resource interfaces:
1 1000Mbps network interface, compatible with 100Mbps/10Mbps networks, requires ESMARC industrial control motherboard to support 1000Mbps networks
● 1 100Mbps network interface, time-division multiplexing with SFP interface
