Abstract
The present invention advantageously provides a motorized roller shade that includes a shade tube, a motor/controller unit and a power supply unit. The motor/controller unit is disposed within the shade tube, and includes a bearing, rotatably coupled to a support shaft, and a DC gear motor. The output shaft of the DC gear motor is coupled to the support shaft such that the output shaft and the support shaft do not rotate when the support shaft is attached to the mounting bracket.
