Cool Pi 4 features an eight-core CPU and an NPU
In the SBC market where Raspberry Pi is located, there are actually Orange Pi, Nano Pi, and other choices, but they are not as big as Raspberry Pi in terms of fame and application range. However, the advantage of these Pis is that they will use more powerful chips, and now there is a single-chip computing board called Cool Pi 4, equipped with RK3588S SoC.
This Cool Pi 4 is developed by a Chinese manufacturer. Its PCB size is 85*56mm, which is the same as Raspberry Pi. The official also stated that it is compatible with the development of Raspberry Pi, but it is up to the developer to study how well this is supported and whether it can replace the original version. Currently, it can install systems such as Ubuntu, Debian, and Android. If you are interested, you can go to their official community first.
In terms of onboard interface support, Cool Pi 4 has 40pin GPIO, two USB 3.0, two USB 2.0, a Gigabit LAN port, and dual-band Wi-Fi and Bluetooth 5.0, etc., The display interface includes mini DP, MIPI SI interface, and HDMI 2.1 display output that supports up to 8K60, which is also rare on SBC.
