This guide will help new users to quickly setup our QSBASE93 Linux Development Kit.

Detailed information about the QS93 solder-in module itself is available on our website.


When opening the package of the Development Kit you should find the following components inside:

  1. The evaluation board “QSBASE93”.

  1. An USB-C cable which is used for power-connection and flashing.

  2. An Micro USB-B cable which is used for debugging.

  1. Our catalog.



Connect the QSBASE93 board as shown in the image below.

  1. Connect the USB-C to the board. The other side is also connected with your host computer.

  1. Verify the Bootmode-jumper is not in Download-Mode. You can also remove it. For help see Enabling USB-Bootmode.

  1. Connect the Micro USB cable to the DEBUG port on the board. The other side is also connected with your host computer.
