A USB hub with per-port power and data disconnects + dev board + I2C, GPIO, and SPI bridges

...

Programmable USB Hub is part of the Microchip Get Launched 2019 design competition!

...

  • A power supply, providing 6 A of 5 V power to downstream devices and 13 mA resolution monitoring (per-port). Port power is individually limitable and switchable.
  • A USB to TTL Serial adapter.
  • A flexible embedded electronics test and development tool. USB data pairs are individually switchable, allowing you to emulate device removal and insertion via software.
  • Mountable.

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
  4. Difference between a crystal, and a crystal oscillatorhttps://www.avrfreaks.net/comment...
