Mega IO Expansion Shield V2(SKU:DFR0165)
SuperMiguel 2012-06-08 18:52:03 3319 Views3 Replies It says it has Servo power in… Does it have a regulator built in? if i connect 12v to it it will bring it down to 5v?
Also when i connect power to those pins, and use the power switch to the PWR position which pins does it power???

2012-06-09 02:34:24 The Switch in the schematic is in the lower left side labled: "SW BD-6"
when you supply 12Vdc it will be provided to anything that is connected to "Vcc"
which is the pins in the top right section of the schematic.

[font=arial][size=small]The switch lets you choose between 5V supplied from the MEGA or an external voltage provided through the power terminal. The power terminal is unregulated voltage which is being supplied to the power pins on the expansion shield so if you connect 12Vdc to it you will effectively be providing 12Vdc to all the devices connected to those pins.[/size][/font]

Sorry but i dont see the switch on the datasheet, can you tell me if i put 12v there which pins are getting 12v? SuperMiguel
