As sales for Myo ended in October 2018, Myo software, hardware, and SDKs are no longer available or supported.
You can still use Myo for gesture-based input control. Google (which acquired North in June 2020) does not collect user data from Myo armbands. Myo was not designed or intended to be used as a medical device.
