Boards and sensors for the arctic
Documentation of the connections from the board to the sensors.
Click on each photo for more detailed info.
One of the boards looks slightly different, as it was the prototype board for the final board layout.
It hooks up to the SparkFun Rh/T sensor, and the gas sensor has a 4pin hookup, instead of 3pins.

The whole board without connections.
Bottom to top:
2 pins: GND and 3.3 V on the MiniBee (left to right)
11 pin header: GND, RAW and analog pins on MiniBee (left to right)
2 pins: GND, RAW - battery connections (left to right)
Left 3 pins: D13, D11, D12 (bottom to top)
Left 4 pins: connections to Rh/T, (DATA, GND, Vcc, Clock) (top to bottom)
Mid 3 pins: connections to Gas sensor, (GND, Vcc, input) (left to right)
Right 6 pins: connections to accelerometer (CS (=Vcc), MISO (=GND), MOSI (=SDA), SCL, GND, Vcc) (bottom to top)
Connection to the gas sensor. Black marked wire should be on the right.
Connection to the Parallax Rh/T sensor.
Connection of the 4 pin connector.

Another closeup of the connection to the Parallax Rh/T sensor
Closeup of the connection on the other side of the Parallax Rh/T sensor.
Single pin connection (Vcc) on the left pin.
Should be opposite of the Data pin on the other side.
Connection of the accelerometer.
Vcc (black line on board) to the black lined cable.
On the board, the cable is the furthest away from the MiniBee connections.
