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.

PT1000 temperature sensor

Hygrosens TEMOD-I2C-R1

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.

Caution: The connection is not 1:1

Multi board connections

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.
