BEFORE YOU BUILD
Frequently asked questions
What processor does Sige3 use?
Sige3 uses the Rockchip RK3568B2 with 4 × Cortex-A55 up to 2.0GHz. It is a complete single-board computer, with onboard network and display connections.
Can I expand the storage?
Yes. The documented storage interfaces include onboard eMMC, MicroSD and M.2 Key M · PCIe 3.0; verify lane configuration for the board revision. Check mechanical clearance, SSD compatibility and system support before installation.
Which Type-C port is for power?
Use the dedicated power input identified in the hardware diagram. The other Type-C connector serves data or OTG functions. Follow the Sige family power guide.
Can I attach Raspberry Pi accessories?
The 40-pin header exposes familiar peripheral signals. Check the exact pin assignment, voltage, driver and device-tree configuration before attaching an accessory.
How do I start with AI inference?
The documented NPU capability is 1 TOPS. Use the matching Rockchip toolchain and image for supported models, then validate model accuracy and real application performance.
