The long awaited RPi 4 is almost finally here! Except we’re not talking about Raspberry Pi 4, but Rock Pi 4 designed by Radxa team, back after three years following the launch of Radxa Rock 2 Square, with the new SBC just unveiled by Tom Cubie, Radxa founder.
Rock Pi 4 single board computer is powered by a Rockchip RK3399 hexa-core processor coupled with 1 to 4GB RAM, and following Raspberry Pi 3 and ASUS Tinker board form factor.
There will be two variants with Rock Pi 4 Model A and Model B sharing most of the same specifications:
- SoC – Rockchip RK3399 big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 1.8 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 – 1, 2 or 4GB LPDDR4 @ 3200 Mbps
- Storage – eMMC module socket, micro SD card slot up to 128GB, M.2 NVME SSD socket
- 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
- Rock Pi 4A – Gigabit Ethernet
- Rock Pi 4B – Gigabit Ethernet with PoE support (additional HAT required), 802.11ac WiFi 5, Bluetooth 5.0 with on-board antenna
- USB – 1x USB 3.0 host port, 1x USB 3.0 OTG port, 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
So the only real difference between model A and model B is the latter includes a wireless module, and optional support for PoE.
Tom Cubie did not inform me about pricing, and there’s no such info on the website that I could find, but LinuxGizmos reports the Rock Pi Model A will sell for $39 (1GB), $49 (2GB) and $65 (4GB), while the Model B will go for $49 (1GB), $59 (2GB) or $75 (4GB).
