Programmable USB Hub

by Capable Robot Components

Image of Board

In addition to being a 4-port USB 2 High-Speed hub, this Programmable USB hub is also:

  • A CircuitPython based development board.
  • A bridge between your computer and I2C (via Sparkfun Qwiic connectors), GPIO, and SPI (via its mikroBUS header).
  • A power supply, providing 6 A of 5 V power to downstream devices and 13 mA resolution monitoring (per-port).
  • A USB to TTL Serial adapter.
  • A flexible embedded electronics test and development tool.
  • Mountable.
  • Functionally flexible. Open source python drivers on the upstream host and Python firmware on the internal MCU allow the behavior of this USB hub to be easily changed to suit your application and environment.

Release Notes for 4.1.0

CircuitPython 5.0.0-alpha.4

This is the latest unstable release of CircuitPython that will work with the Programmable USB Hub.

Unstable builds have the latest features but are more likely to have critical bugs.

Release Notes for 5.0.0-alpha.4

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for it. They are stored on Amazon S3 by language (some which may be unreleased.) Try them if you want the absolute latest and are feeling risky.

Past Releases

All previous releases are available on GitHub. They are handy for testing but we recommend the latest stable otherwise.
