Cute

By M.Lakshmi from N/A on May 22, 2017
Module is nice, but Some times it is working when 5v and gnd is applied, in some cases it not exactly working [If 5v and gnd is applied and then switch on the power supply the D0 led is also on; actually power led will only on, D0 is on when touch/ vibrate then only D0 led will on ] what is the problem its manufactures problem or testing problem
