大家好,我是小月月牙,你们是否还记得不久之前的我们写过一篇关于 RPI 4B的文章 (戳我回看
)。
ROCK 4B是一款Radxa公司研发出的一款开发板,它拥有强大的六核ARM处理器,内置RK3399, 与其他流行的SBC主板相比,性能显着提升。
板 卡 配 置
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
Connectivity -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 power via a 5V/3.4A power adapter, but it is not
recommended
Dimensions –85 x 54 mm
板卡GPU
ROCK Pi4B采用基于ARM的RK3399 SoC,配备六个内核,可增强多线程应用性能, 它提供4核和600MHz时钟速度。
与竞争对手的SBC GPU相比,ROCK Pi 4B提供更好的GPU计算和GPU加速性能。
IO性能
ROCK Pi 4B具有多种存储选项,可在外部存储驱动器上提供卓越的读写性能,从而实现更快的读写速度。 这改善了工作流程,复制,备份和整体文件使用。
小编觉得,最大的亮点是硬件接口与树莓派官方板子兼容。
不止是板子尺寸,40Pin IO和显示接口都与树莓派是通用的。比如树莓派官方的7寸显示器,树莓派官方的CSI相机,都可以在RPI 4上使用。
