Mounting
Use high quality cable, PVC cable gets very stiff in cold temperatures. All parts have to be put into shrink tube to isolate it from any conductive or electrostatic plastic. Some pictures below do not show this tube for better visibility.
Autopilot
Solder the BEC to the Umarim. Cover the Umarim in shrink tube. Cut free the Molex connector openings

Modem
Solder the cables to the XBee explorer board, plug cables in 5-pin Molex connector. Secure cables on explorer board with hot glue. Plug XBee modem into explorer board and secure with shrink tube.
Recent Sparkfun boards (v14) are equipped with 3.3V to 5V converters. Although the Umarim/LPC2148 should be able to handle 5V it is safe to not use the converters. Remove R5, R6, R7, R8, Q1, and Q2 from the XBee explorer regulated breakout board. Bridge OUT-DOUT and IN-DIN within the transistor footprint.

Solder a second wire (not shown in picture) from the XBee to the TWOG so that the data sent by the Umarim can be logged. That means that two wires are to be connected at the XBee DIN pin.

MLX90614 infrared thermometer
Use MLX90614 adapter board from Paparazzi hardware repository. Solder parts, take care of sensor polarity. The I2C address of the MLX90614 needs to be programmed once before it can be used. Connect it as the only sensor to I2C and flash/run it with the IR_MLX_ONE_TIME_CONFIG option set (currently available in the master and campaign2013 branch). See Module/Melexis_MLX90614.

PT1000 temperature sensor
Solder the PT1000 sensor (little blue on the picture) to the two correct pads at the edge of the TEMOD-I2C-R1 board, where the pin plugs are. The pads on both side are not connected through. It has to be soldered to the side not carrying the chip. Remove pin header from TEMOD board. Solder 4pin cable to TEMOD, it will be connected to the Umarim through the multi_i2c board below. Fix cables with hot glue. Put some hot glue on the top of teh board, just behind the PT1000. Seal the board with shrink tube.

Multi Board
Use the multi board from the Paparazzi hardware repository to have multiple I2C connections, a MS5611 barometric pressure sensor, a 3.3V to 5V level shifter and servo JR connectors for BEC supply through the motor controller. Drill/burn holes into the shrink tube at the hole locations to attach the board with screws later on.
