Low Speed Expansion Connector 3

This is an additional connector that is not required by the 96boards specifications.

It provides:

  • 4¬†Qualcomm sensor core QUP interfaces
  • Interrupts signals for sensors
  • Additional GPIOs and power supplies

GPIOs labelled QUP have additional low speed interface capabilities (UART, SPI, I2C).  Several GPIOs can be used to wake up the application processor.
