This series reorganizes RK3568 Hardware Design Guide V1.1 (Chinese, 2021-06-08) and the separate High Speed PCB Design Guide V1.0.0 (English, 2021-04-12) around engineering questions. ArmSoM Sige3 uses RK3568B2. Its board documentation provides a product reference for studying and evaluating these design topics. SoC reference circuits do not describe every Sige3 circuit or exposed interface. Confirm SDK/BSP, kernel, silicon revision, firmware and peripheral combinations. Values are source references, not ArmSoM hardware measurements.
Choose a design topic
- RK3568 minimum system: clocks, reset, boot and debug
- RK3568 power and IO domains: RK809-5, discrete rails and standby
- RK3568 DDR design: devices, topology, ECC and routing constraints
- RK3568 boot storage: eMMC, FSPI, NAND and SDMMC circuits
- RK3568 high-speed expansion: USB, SATA, PCIe muxing and clocks
- RK3568 Ethernet hardware: dual GMAC, RGMII and QSGMII
- RK3568 display and cameras: VOP, MIPI, HDMI and power
- RK3568 audio and control: I2S, UART, SPI, CAN and I2C
- RK3568 PCB design: stackup, escape routing and return paths
- RK3568 production review: thermal design, ESD, assembly and storage
Scope and use of this series
Read from minimum system through power, memory, storage, high-speed IO, networking, multimedia, controls, PCB and production. The two PDFs are not matching language editions; their distinct scopes are identified. This is an engineering-topic reorganization, not a replacement for every pin map, topology table or device list in the originals. Check the originals, current TRM, errata and actual SDK before implementation.
The source-page screenshots preserve circuit labels and context; article text and parameter tables remain editable. No matching English edition of the main Chinese guide was supplied, so its figures remain Chinese in all four languages. Images from the separate English PCB guide are labeled accordingly. Page references are physical PDF pages.
