Oct 23, 2023 — by Giorgio Mendoza 801 views

Launched just last month, the Dusun Pi4 is a feature-rich alternative to the popular Raspberry Pi 4. Powered by a Rockchip RK3568 with a 1TOPs NPU, this device emphasizes performance, extensive connectivity options, and ample storage capacity.

Unlike the previously covered Home Assistant Green, which is based on the RK3566 SoC, the Dusun Pi4 (DSGW-290) features the following Rockchip System-on-Chip:

  • RK3568 — 64-bit, Quad-core Arm Cortex-A55 (up to 1.8GHz); Arm Mali-G52 GPU; 1TOPs NPU

    Dunsun avalability outside China looks to be non-existing. Also sad that Dunsun do not seem to maintain/update their documentation and development tools for their DSGW-210 series, epecially their DSGW-210-HA that came with Home Assistant which is now broken.
