Engineering inferenceRated 4.4 A (2C) max continuous by the maker — enough for small motors and servos next to the controller; Adafruit advises keeping sustained draw near 1 A.
Engineering inferenceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.
Supply range 3–4.2 V.
