ROC-RK3399-PC Plus

Six-Core 64-Bit High-Performance Main Board

Equipped with high-performance RK3399 processor and adopts multiple power supply modes. It supports WIFI or BT wireless connection and can be connected to the expansion board, making the performance stronger and superior. When combined with the all-aluminum alloy case, it becomes a pocket portable personal computer.

High-performance Core Processor

With"server-level" dual-core Cortex-A72+ 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.

Portable Personal Computer

With unique model design and the size is only 120 x 72 x 11.2mm. When combined with the all-aluminum alloy case, it becomes a pocket portable personal computer.

Expansion Board Combination

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

Strong Network Capability

Supports Gigabit Ethernet, 2.4GHz Wifi and Bluetooth4.2, as well as owns strong Network expansion capability.

Multiple Operating Systems

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

Multiple Power Supply Modes

The main board can be powered by DC 12V, POE+ (802.3 AT, output power: 30W) via the expansion board or dual-cell battery. With multiple power supply modes, it can cater to the demands of users in different scenarios, making it more flexible and convenient to use.
