Yes. The Vernier myDAQ Adapter is designed to connect with the NI myRIO, as well as the NI myDAQ.
Vernier myDAQ Adapter (BT-MDAQ)
Both the myDAQ and myRIO have the same 20-position screw terminal with the exact same input/output pins. Therefore, you can use the myDAQ Adapter with the myRIO.
We have posted LabVIEW examples for using the myDAQ Adapter with the myDAQ. However, the myRIO uses a different driver, and these examples will not work with myRIO.
