RK3399 SBC offers dual Type-C with DP and optional PoE

Jun 25, 2018 — by Eric Brown 5,480 views

Libre Computer unveiled a “ROC-RK3399 (Renegade Elite)” SBC that runs Android Oreo or mainline Linux 4.19+ and offers GbE with PoE, HDMI 2.0, 2x USB Type-C with DP, 3x USB 2.0, and dual 60-pin headers.

Libre Computer has posted some photos and preliminary specs of a ROC-RK3399 (Renegade Elite) board follow-on to last year’s Indiegogo launched Renegade SBC. The Renegade Elite will launch on Indiegogo in July with general availability due in August. The original Renegade eventually went on to be re-sold by T-Firefly as the Firefly-ROC-RK3328-CC, and a similar future appears to await the Renegade Elite, as the photos show the board imprinted with the Firefly logo.

As the ROC-RK3399 name suggests, the Renegade Elite, heard about from a Liliputing post, is built around the high-end Rockchip RK3399 SoC. The SoC features 2x Cortex-A72 cores, which are typically clocked up to 2.0GHz, as well as 4x -A53 cores and a Mali-T860 GPU.

The Renegade Elite is larger than the Raspberry Pi sized Renegade, which ran on a quad -A53 Rockchip RK3328, but is smaller than the more feature-rich Firefly-RK3399. (For other RK3399 boards see our catalog of 116 open-spec hacker boards.)


There’s still no price, and the specs are missing a few details. Like the Renegade, this will almost certainly be an open source board, although the Source Code and Download tabs on the preliminary product page are currently empty. The SBC supports Rockchip Linux 4.4, mainline Linux 4.19+, and Android 8.0 (“Oreo”).


The Rockchip RK3399 is accompanied by 4GB LPDDR4 RAM, and there’s an eMMC socket and a microSD slot. There’s no onboard wireless, but you get a GbE port with optional Power-over-Ethernet.

The Renegade Elite is equipped with dual USB 3.0 Type-C ports that support DisplayPort as well as USB functions, and one of them is designed as a power input for the 12V SBC. Three USB 2.0 ports are also available along with an HDMI 2.0 port, an eDP interface, and a mix of MIPI-DSI and CSI interfaces.

Unlike many RK3399 board, there are no discrete audio interfaces to exploit the SoC’s exceptional audio talents. Presumably, the HDMI 2.0 port supports audio, however. In place of the Renegade’s Raspberry Pi-style 40-pin expansion connector you get 60-pin high-speed PCIe and 60-pin low-speed connectors that likely include audio among many other interfaces.

    Everybody talk about the interesting specification of the RK3399. I have one board (OrangePi lite 2), and it is not possible to use the GPU as there are no userspace drivers and no DRM-X11 interface. So with this “fantastic board” I’m not able to play a simple 1080p H264 video. I agree that this is due to vendor lack of support, but in the end a raspberry pi has better performances. I think it could be interesting to describe this access to the several device regarding the OS when describing such board. It will avoid the potential buyer a lot of future issues.

    Dual display support in SOM-RK3399 board(Friendly ELEC):

    I tried connecting type-C to HDMI cable to SOM-RK3399 board(Friendly ELEC). But display is not coming up.

    Need your help for the exact steps and the required cable details.

    Thank you.
