I bought a grove starter kit for arduino V3 and I connect it with my udoo neo board. The voltage switch on the grove arduino shield is set to 3V3. All grove modules are running well except the lcd module. The backlight is working but I can't display anything on it. It seems that the problem is related to input voltage ? http://www.seeedstudio.com/forum/viewtopic.php?f=69&t=6425&p=22884&hilit=lcd#p22881 Can I try to set the voltage switch on the arduino grove shield to 5V without any risk ? If not any solution to fix the problem ? Many thanks, Frédéric.
Dear frichez, I suggest to try, it shouldn't damage the board, but if it happens tell us since I told you to do that
