Is it ok to use external power supply for PointWrite Touch module? If yes, what is the spec. of the power adaptor?


It is ok to use the adapter 5V/2A for PointWrite Touch module. If the spec is 2.4A, it is also fine. Please make sure not to keep PointWrite Touch connecting with power adapter if the projector had been turned off. Otherwise, it may damage the laser module of PointWrite Touch.
