RFID reader hookup problems with Redboard

[Will_Jarmer]

i am trying to hook up the RFID reader with a Redboard. I

n the hook guide they are using a redboard artimis. do i have to have that one? i get flickers form RX and TX , making me think the power is an issue on this board or a connection. i am needing help using this red board.

Some solder on those pin header connections would be a good start if you suspect an intermittent connection.
