foreword
Develop RK3399 and other related projects and products for evaluation. Recently, I found that Rock Pi4 is a good evaluation version. The price is reasonable and can meet the evaluation development. Just like the Raspberry Pi, the pin interface is reserved. It is a good fast landing arm. One of the better options for a range of products and projects.
This film will start the journey of the Rock Pi platform.
There are multiple products in the Rock Pi series
Zero: Based on Amlogic S9-5Y2
The SoC used in the Radxa Zero is the Amlogic S905Y2. The main system CPU is a quad-core ARM Cortex-A53 CPU with unified L2 cache to improve system performance. Additionally, the Cortex-A53 CPU includes a NEON SIMD co-processor for increased software media processing capabilities. The graphics subsystem consists of two graphics engines and a flexible video/graphics output pipeline. The ARM G31 MP2 GPU supports OpenGL ES 3.2, Vulkan 1.0 and OpenCL 2.0, while the 2.5D graphics processor handles additional scaling, alpha, rotation and color space conversion operations.
ROCK 3: Based on Rising Micro RK3568
ROCK3 is Radxa's SBC (Single Board Computer) series based on Rockchip RK3568. It can run android or some Linux distributions. ROCK3 comes in two models, A and B, with 2GB, 4GB, 8GB memory options for A, and 4GB and 8GB for B.
ROCK3 features quad-core Cortex-A55 ARM processor, 32-bit 3200Mb/s LPDDR4, up to 4K@60 HDMI, MIPI DSI, MIPI CSI, 3.5mm jack with microphone, USB port, GbE LAN, PCIe 3.0, PCIe 2.0, 40-pin color expansion header, RTC. In addition, ROCK3 supports USB PD and QC power supply.
*ROCK Pi 4: Based on Rising Micro RK3399
Price range: 400~1000, different configurations have different prices, divided into emmc and no emmc.
ROCK Pi 4 is Radxa's SBC (Single Board Computer) based on the Rockchip RK3399. It can run android or some Linux distributions. ROCK Pi 4 features a hexa-core ARM processor, 64-bit dual-channel 3200Mb/s LPDDR4, up to 4K@60 HDMI, MIPI DSI, MIPI CSI, 3.5mm microphone jack, 802.11 ac WIFI, Bluetooth 5.0, USB port, GbE LAN, 40-pin color expansion header, RTC. In addition, ROCK Pi 4 supports USB PD and QC power supply. ROCK Pi 4 comes in two models, Model A and Model B, each with 1GB, 2GB or 4GB memory options.
*ROCK Pi S: Based on Rising Micro RK3308
Price Range: 100~200
The ROCK Pi S is Radxa's SBC (Single Board Computer) based on the Rockchip RK3308. Equipped with a 1.7-inch size 64-bit quad-core processor, USB, Ethernet, wireless connectivity and a voice detection engine, it is ideal for IoT and voice applications. The ROCK Pi S is available in two memory sizes, 256MB or 512MB DDR3, and uses a uSD card for the operating system and storage. Optionally, the ROCK Pi S can be supplied in an onboard storage version with 1Gb/2Gb/4Gb/8Gb NAND flash.
ROCK Pi E: Based on X86 chip
The ROCK Pi X is Radxa's first X86 SBC (Single Board Computer). It can run Windows and Linux distributions. The ROCK Pi X was launched after the Radxa team received numerous users asking if the ROCK Pi 4 could run Windows. ROCK Pi X with Intel Cherry Trail Quad Core Processor Z8350, 64-bit Dual Channel 1866Mb/s LPDDR3, Up to 4K@30 HDMI, 3.5mm Jack with Mic, 802.11 ac WIFI, Bluetooth 4.2, USB Port, GbE LAN, 40 Pin Color Extension Header, RTC. In addition, ROCK Pi X supports USB PD and QC power supply. The ROCK Pi X comes in two models, Model A and Model B, each with 1GB, 2GB or 4GB memory options. For detailed differences between A and B types, please check the specifications.
ROCK Pi N10: Based on Rising Micro RK3399Pro
The price range is about 1000~2500, and the price is different for different channels and different configurations.
The ROCK Pi N10 is Radxa's SBC (Single Board Computer) based on the Rockchip RK3399pro.
Summarize
Through the above comparison, combined with the current mainstream localization bias of RK and RV, ROCK Pi 4 (based on RK3399) is recommended, and ROCK Pi S (based on RK3308) for IoT, which can eliminate the production of uboot, kernel, and rootfs. Make the customer only care about the application, of course, if the new device is added, the driver is still an inevitable part.
However, rock pi has saved us some stability-related problems of uboot, kernel and rootfs, which can make the product solutions that can use this series land quickly.
