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
Board Card GPU
ROCK Pi4B uses the ARM-based RK3399 SoC with six cores, enhancing multi-threaded application performance, providing 4 cores and a 600MHz clock speed.
Compared to competitors’ SBC GPUs, ROCK Pi 4B offers better GPU computing and GPU acceleration performance.
IO Performance
ROCK Pi 4B features multiple storage options, providing excellent read and write performance on external storage drives, resulting in faster read and write speeds. This improves workflows, copying, backing up, and overall file usage.
The biggest highlight is the hardware interface compatibility with the official Raspberry Pi boards.
Not only the board size, but the 40Pin IO and display interfaces are also compatible with Raspberry Pi. For example, the official Raspberry Pi 7-inch display and the official Raspberry Pi CSI camera can be used on the RPI 4.
