Accelerometer mounted on Z Sensor Board

Please read through the entire instruction manual before beginning your kit.

It is assumed that you have experience building electronic circuits. The most challenging aspect of this kit is to mount the accelerometer. There is an accelerometer on the XY Sensor Board and the Z Sensor Board.

The through hole mounting of the components is relatively simple. When mounting the OPA4342PA and OPA2430PA care must be taken to not to overheat the chip. If you are unsure of your soldering technique here, you may want to use 14 Pin DIP sockets from Radio Shack (Cat # 276-1999).

To test the controller board, you will have to construct a serial cable. We include the cable and the board site end in the kit, however, you will need to provide the DB-9 connector (Radio Shack Cat # 276-1538) and housing (Radio Shack Cat # 276-1508).

It is helpful to use a .1inch 10 Position connector as a fixture to hold the .1inch Headers in alignment while soldering.

Use a small amount of solder to secure the crimp terminals used in the 3POS and 4POS .1inch connectors.

It is helpful to use a piece of tape to hold components in position while the board is turned over for soldering.

Verify the alignment of chips before applying solder. The notch in the chip must align with the notch silkscreened on the printed circuit board. The accelerometers have a small dot on the bottom of the chip. There is a corresponding dot in the square arrangement of pads.
