Boards and sensors for the arctic

July 27th, 2009

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.

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)

Single pin connection (Vcc) on the left pin.
Should be opposite of the Data pin on the other side.

Vcc (black line on board) to the black lined cable.
On the board, the cable is the furthest away from the MiniBee connections.
