The low-costSBC was unveiled in 2018 with a Rockchip RK3399 processor, up to 4GB RAM, and Raspberry Pi 3 form factor.Rock Pi 4 Plusbuilds on the relatively popular single board computer with an upgrade toprocessor, which is a higher performance RK3399 SoC typically used in Chromebooks and.
The new board also adds 16 to 128 GB eMMC flash, instead of relying on an optional eMMC module, and will come pre-loaded with Twister OS Armbian lightweight desktop OS based upon Armbian Focal 20.04.1 LTS (aarch64) for Rockchip RK3399-based SBCs.
Four variants of Rock Pi 4 Plus share most of the same specifications:
SoC – RockchipOP1big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @up to 2.0 GHz, 4x Cortex-A53 @ up to 1.4 GHz, a Mali-T864 GPU with support OpenGL ES1.1/2.0/3.0/3.1, OpenVG1.1, OpenCL, DX11, and AFBC, and a VPU with 4K VP9 and 4K 10-bit H265/H264 decoding
- System Memory & Storage
Rock Pi 4B Plus B2E16 – 2GB RAM + 16GB eMMC flash
Rock Pi 4B Plus B4E32 – 4GB RAM + 32GB eMMC flash
Rock Pi 4B Plus B4E64 – 4GB RAM + 64GB eMMC flash
Rock Pi 4B Plus B4E64 – 4GB RAM + 128GB eMMC flash
- Common
MicroSD card slot
M.2 socket for NVMe SSD (M.2 extension board plus heat-sink is recommended for proper mounting)
4MB SPI flash soldered with NVMe booting from SPI supported
- Video Output / Display Interface
HDMI 2.0a up to 4K @ 60 Hz
2-lane MIPI DSI via FPC connector
Dual independent display support
Audio – Via HDMI and 3.5mm audio jack; HD codec supporting up to 24-bit/96Khz audio
Camera – MIPI-CSI2 connector for camera up to 8MP
- Connectivity
Gigabit Ethernet with PoE support (additional HAT required)
Dual-band 802.11ac WiFi 5, Bluetooth 5.0 with on-board antenna (external antenna also supported, but an u.FL connected must be soldered)
USB – 1x USB 3.0 host port, 1x USB 3.0 OTG port (host/device selectable by switch), 2x USB 2.0 host ports
Expansion – 40-pin expansion header with 1x UART, 2x SPI bus, 2x I2C bus, 1x PCM/I2S, 1x SPDIF, 1x PWM, 1x ADC, 6x GPIO, and power signals (5V, 3.3V and GND)
Misc – RTC
Power Supply – Via USB-C port supporting USB PD 2.0 (9V/2A, 12V/2A, 15V/2A, or 20V/2A) and Qualcomm Quick Charge 3.0/.0 (9V/2A, 12V/1.5A). It’s also possible to power the board via a 5V/3.4A power adapter, but it is not recommended
Dimensions – 85 x 54 mm
There’s some conflicting information about the specs, as the newsletters’ announcement lists four models, two model B as above, and two model A without WiFi:
Model A 2GB LPDDR4 + 16GB eMMC: 49$
Model A 4GB LPDDR4 + 32GB eMMC: 65$
Model B 2GB LPDDR4 + 16GB eMMC: 59$
Model B 4GB LPDDR4 + 32GB eMMC: 75$
But for example, Aliexpress lists four model B boards with up to 128GB eMMC flash, albeit the largest capacity is not available (yet).
The original Rock Pi 4 would not ship with an operating system since internal storage did not include, but since Rock Pi 4Plusdoes include at least 16GB of eMMC storage, Radxa decided to flashto the board maintained by Pi Labs.
Twister OS Armbian version of Twister OS specific to Rockchip RK3399/OP1 board such as Rock Pi 4B,, andboards. It should be noted that 4 GB of RAM is recommended, so the versions of the board with 2GB RAM may not work in an optimal manner. Twister OS Armbian relies on XFCE desktop, arecent Linux kernel, and supports hardware video decoding, as well as 2D/3D GPU acceleration.
