大家好,我是芯板坊,今天小编带来了大家期待已久的 RPI 4B!
惊不惊喜, 意不意外 ! 核心是瑞芯微 RK3399 , USB3.0 和 USB Type C
。有三种内存规格的版本,分别是1、2或4GB DDR4。
有眼尖的小伙伴应该已经发现了,这次的RPI 4B并不是Raspberry Pi4,而是 Rock Pi 4B
,来自Radxa。大家一开始都被小编给忽悠了吧。啊哈哈哈哈!!!!!
这个RPI 4的具体参数如下,与树莓派3B相比,还是有很大进步的,也许还超越了即将推出的树莓派4B。
配置如下
- 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
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。
不过,很遗憾的是,硬件接口虽然接上了,软件驱动还没有支持。Radxa团队现在正在完善驱动程序。
目前,板子还没用公开销售,但是Radxa在linuxgizmos上透露了可能的售价,
1GB版本售价49美元,2GB版本售价59美元,4GB版本售价75美元。
