EDGE / Edge Compute Mainboard
Rockchip RK3588 · Octa-core 2.4GHz · 6 TOPS
This board uses the Rockchip RK3588 octa-core processor, with a frequency up to 2.4GHz, a Mali-G610 GPU, and an NPU of up to 6 TOPS. The system is Debian 12. Display, Gigabit Ethernet, Wi-Fi 6, Bluetooth 5.4, and 4G/5G expansion are on the same board. Zhcloudlink supports custom mainboards and also supports edge compute hardware.
Overview and Features
The GPU is compatible with OpenGL ES 1.1/2.0/3.2, OpenCL 2.2, and Vulkan 1.2. It integrates LVDS, eDP, MIPI, Gigabit Ethernet, Wi-Fi 6, Bluetooth, 4G, 5G, a 5W×2 amplifier, a TF card, infrared remote control, serial and IO, HDMI, MIC, and backlight power. It can decode common video and image formats and drive a TFT LCD. It is suited to AI servers, face payment, security, healthcare, transportation, industrial control, smart education, and smart retail.
- High integration: USB, LVDS, HDMI output, Ethernet, Wi-Fi 6, and Bluetooth are together, and a TF card can be inserted.
- Expansion interfaces: 2 USB 3.0, 2 USB 2.0 ports, 4 expandable serial ports, 4 GPIO, and 1 4G PCIe.
- RKNN NPU up to 6 TOPS. Memory can be selected up to 32GB.
- Serial is 4 TTL channels, of which 2 can be changed to RS232 and 2 can be changed to RS485.
Zhcloudlink can customize the mainboard for a project and supply matching edge compute hardware. One USB 3.0 can be removed and replaced with a TYPE-C compatible with DP 1.4, up to 8K@30fps.
