Hey, guys! I'm newbie here...I bought the main board and his daughter for make the IMU for my Quadcopter:1 x ArduIMU Sensor Board - Six Degrees of Freedom (Main)2 x ArduIMU Sensor Board - Six Degrees of Freedom (Daughter)So, I wanna make a control board with the Jordi's "ArduIMU+" parts on the same board with an ATMEGA8 or latter, attaching it to my Seeeduino. By that way, all the filter things will be processed by the second chip. The first problem is: looking at the diagram I don't identified what is the 741G3157DBVR chip. I wanna substitute it, because my board will don't use SMD components. In fact I will substitute all them to the "through role". Does somebody help me with it?I'm doing the frame with Pu resin and carbon-fiber sticks. Until now it have 75g of weight. I'm very happy with the starting point. :)

The 741G3157DBVR is a single 1 to 2 multiplexor, also know as the 74ls157 or 74157, etc. But they normally come in 4.
