Some computers and Chromebooks only have USB-C or Thunderbolt ports and no USB-A ports. Such devices include all Apple MacBook Pro and MacBook Air models, as well as some many Dell, HP, and Lenovo laptops. Many Chromebooks also have only USB-C ports.

A USB-A port is rectangular and has been used for about 20 years. A USB-C port is much smaller than a USB-A and is distinct from a mini or micro USB port. Thunderbolt 3 ports are physically the same as USB-C and are compatible with USB-C, but they have additional capabilities.

Computers and Chromebooks with only USB-C ports will require either an adapter or a native USB-C cable to use Vernier USB products. Whenever possible, we recommend using a native USB-C cable rather than an adapter.

Vernier products come with cables utilizing USB-A for connection to computers and Chromebooks and, in some instances, charging. USB-C cables are sold separately. We offer the following USB-C cables for use with our products USB products:
Mini USB-C Cable (CB-USB-C-MINI)
Micro USB to USB-C Cable (CB-USB-C-MICRO)

Which cable you need depends on the type of USB connector the Vernier product uses. Some products use a mini-USB connector, some use a micro-USB connector, and some use a standard USB connector. The table below identifies which cable will work for a particular Vernier product.
