About the Usb host hub PCB

Usb host hub is an open source RP2040/RP2350 PCB design by apistol78, published on GitHub. It is a 2-layer board measuring 129 × 41.9 mm, with 52 components from 24 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the FE1.1s, W25Q128JVS, AZ1117EH-3.3TRG1 and USBLC6-2SC6. By type, the board carries 22 capacitors, 15 resistors, 7 ICs, 5 connectors, 2 crystals and 1 diode.

It belongs with the audio designs in this gallery.

From the project

Risc-V pipelined CPU and SoC written in SystemVerilog

After everything has been built you should be able to run the emulators:

Written using SystemVerilog and are split up into logical pieces where each stage of the pipeline is in a separate module:

Usb host hub: common questions

What microcontroller does the Usb host hub use?

The Usb host hub is built around the RP2040, from the RP2040/RP2350 family.

How big is the Usb host hub PCB?

The Usb host hub measures 129 × 41.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Usb host hub?

52 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Usb host hub design files?

From the apistol78/rv32 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Usb host hub design in my own project?

The repository has no license, so all rights stay with apistol78. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Usb host hub without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
