Six-Core 64-Bit High-Performance Main Board

ROC-RK3399-PC adopts Rockchip high-performance core configuration, unique multiple power supply mode and unique plate design. It can be connected to the expansion board, making the performance stronger and superior. When combined with the metal casing, it becomes a pocket portable personal computer.

Built-in strong core configuration

With"server-level" dual-core Cortex-72+ quad-core Cortex-A53 architecture, the frequency is up to 1.8 GHz, and 4GB LPDDR4 dual-channel 64-bit RAM high-performance memory is configured to comprehensively improve the performance of mainboard.

Small size card computer

Unique plate design, golden ratio, only 120 x 72 x 11.9 mm in size. When combined with the metal casing, it becomes a pocket portable personal computer.

Expansion board combination

The expansion board onboard balanced charging circuit to charge the battery, and it can also be powered by POE+. It has M.2 M-Key interface to expand SSD and M.2 E-Key interface to provide SDIO 3.0 and USB 2.0 signals. ROC-RK3399-PC main board combined with the expansion board can greatly improve the performance.

Support multiple systems

Supports xserver, wayland display framework and multiple operating systems, such as Android, Ubuntu, Debian9, Linux+QT, etc. It has onboard SPI flash and supports boot with TF card, EMMC, SSD, USB flash disk, making system startup more convenient.

Multiple power supply modes

ROC-RK3399-PC can be powered by POE+ (802.3 AT, output power 30W) or dual-cell battery. It has a Type-C PD 2.0 power control chip and supports wide voltage (5V~15V) input. A variety of power supply modes can meet the choices of users in different scenarios.

Rich peripheral interface

It has rich interfaces, such as MIPI/eDP screen interface, dual-channel MIPI CSI(supporting dual-channel cameras), Type-C x 2, USB 2.0 Host x 3, HDMI 2.0, Gigabit Ethernet (RJ45), GPIO, etc.
