i guess i found it when i removed the board ,small letters near the connector

board i have you can barly see it,the bluetooth hides it and the 40 pin sockets covers part of it

It attempting to use the wifi board that is recommended, it draws 300 ma and the EZ-B will go into brownout. Using separate power and a 3.3v regulator is a better option.

yes i saw that,everything on EZB you mostly need a seperate power supply i use 3.3 volt LDO,as for all my power supply designs,all most every battery design uses LDO

@robotMaker, that is untrue. It depends what version you have. The two most recent versions use a 3 amp VR for the Microchip and Bluetooth - the wifi adapter only drawing 200mha wont' affect it at all:)

Also, the only time you need to use separate power is when you exceed the 5 amps on the I/o lines. The I/o is powered by 5 amps, and you can use a simple calculator to figure out how much you're drawing. With a fan, I successfully pull 7-8 amps from my power source.

Thanks DJ ,i just thought from what ROBOT-DOC said that i needed a seperate power supply I do know that WIFI board takes 300ma and thought from what he said that the board has less then 300 ma

i think mostly only SERVO'S need a seperate power supply,i have all my 9 of them version 3

I don't know what other reason causes the Blue flashing LED on the EZ-B to go out when I attempt to power the WiFi chip from the bluetooth connector. When the WiFi is powered from another source the EZ-B Blue LED continues to flash. Of course even though my ASUS router recognizes the WiFi board and the IP address discovered performing the set-up steps there is still no correct communication between the ARC app and the EZ-B. (Tx to Rx and Rx to Tx) results in an error condition that the EZ-B has Version 8.5 and needs to be flashed.
