Why ITXD20B

Four things to know about this board

Platform

Domestic Phytium silicon

Onboard Phytium D2000/8 (Standard Edition) at 2.3GHz with paired X100 graphics — an 8-core architecture for supply-chain independent projects.

Field Bus

Six COM plus 2× CAN

COM1/2 as rear DB9 RS232, COM3/4 RS232/422/485 selectable, COM5/6 RS232 — with 2× CAN and I2C for vehicle- and plant-style buses.

Software

Kylin OS (KOS)

Supported and shipped for the Kylin operating system — specify KOS for the board, BIOS and integration path as one package.

Connectivity

Dual LAN, wireless ready

Two RTL8111H gigabit ports with WiFi, 4G/5G and Bluetooth expansion on top — plus mSATA and SATA 3.0 storage options.

Where It Fits

Compact integrated systems, quietly

The ITXD20B targets compact, highly integrated mini computer systems where the whole unit has to sit close to the user. The card’s own application list says it plainly: industrial control, TV cabinets, home theater computers and smart home devices.

TV cabinet & home theater boxes: low power draw and small footprint suit media consoles where fan noise and space are both limited.
Smart home hubs: 6× COM plus 2× CAN for KNX-style and serial building controls, dual LAN to separate home and uplink traffic.
Kylin-based control points: for projects that must run KOS, the board ships with the OS support baked into the spec.
