Preparing v3 CanSat Shield Radio

The CanSat Shield with radio

On the v3 CanSat shield, as shown on the figure to the right, there are two sets of jumper pins, J2 and J3.

When J2 and J3 is not connected you can program the Arduino.

By setting the jumpers at J2-1 and J2-2 you can transmit data to the radio.

When placing jumpers at J3-1 and J3-2 you enable data storage in the SD-card (if it’s connected).
