README
README.mdrp569
An open hardware board (KiCad) that pairs a Raspberry Pi RP2350B with a WCH CH569W. The RP2350B generates high-speed data and the CH569 streams it to a host over USB 3.0.
Status: v1.0 (tag v1.0). Schematic complete, PCB fully routed (4-layer, 50×70 mm, rounded corners,
parts on both sides; 0 unconnected, 0 DRC errors) and JLCPCB production files generated. Before ordering:
USB pairs as coupled pairs, silkscreen cleanup, impedance check (see docs/layout.md).
First firmware for both chips in firmware/ (builds, not run on hardware yet).
Schematic PDF. Documentation site: https://kelu124.github.io/rp569/ (GitHub Pages from docs/).
Production files (JLCPCB)

hardware/jlcpcb/rp569-bom.csv | Assembly BOM with LCSC part numbers |
hardware/jlcpcb/rp569-cpl.csv | Assembly placement (CPL) |
Board to fabricate: hardware/rp569-routed.kicad_pcb. Regenerate the files
with python3 hardware/gen/gen_fab.py. Two parts are not stocked by JLCPCB and must be consigned: CH569W and the
Amphenol GSB343K33HR USB3 connector (docs/bom.md).

Features
| Block | RP2350B | CH569W |
|---|---|---|
| USB | USB 2.0 on USB-C (firmware, debug, test control) | USB 3.0 SuperSpeed, Micro-B connector |
| Storage | QSPI flash | SD card on the eMMC/SD controller |
| User I/O | RGB LED, 2 user buttons | RGB LED, 2 user buttons |
| Boot | BOOTSEL + RUN buttons | BOOT button + jumper (force the USB bootloader on a blank chip) |
| Breakout | I2C header for extra devices | I2C header (bit-banged GPIO) |
Logic analyser: 8 input pins on the RP2350B are sampled by PIO and streamed over the parallel bus to the CH569, then to the host over USB 3.
Power: the RP2350B runs from either USB connector through a TI TPS2121 power mux, so neither back-feeds the other. The CH569 is powered from its own USB3 VBUS through a load switch that the RP2350B controls, so it can be power-cycled and forced into its bootloader during automated tests.
Links between the two chips
- 8-bit parallel bus with clock and handshake lines (8-bit because the CH569's 16-bit mode shares pins with the SD card; see
specification.mdD-003): RP2350B PIO sends, CH569 HSPI receives. - Shared I2C bus.
- UART.
- CH569 RESET# and boot-mode pins driven by the RP2350B, so the CH569 can be reflashed and power-cycled automatically during testing.

146 parts, built around the CH569W, RP2350B, TLV62569DBVR-TP and W25Q128JVSIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Rp569 KiCad files?
From the kelu124/rp569 repository on GitHub, at the commit this page was made from: the board is hardware/rp569.kicad_pcb and its schematic hardware/rp569.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rp569 design in my own project?
Its repository states no licence, so its author keeps all rights: ask kelu124 before reusing the design.
