 Bigger Bigger  Smaller Smaller  Reset Reset

Hi all, I'm new and a beginner. I'm planning a High Altitude Balloon flight and I was thinking on put together an arduino UNO, the Adafruit GPS Ultimate shield and the radio transmitter Radiometrix NTX2. I searched a lot but I only found how to connect the gps shield to arduino or the ntx2 to arduino, but I haven't found how to put these three parts together. Should I connect the NTX2 to arduino or to the gps shield?
Can anyone help me?
Thank you very much

You can hook both to the Arduino.  Just pick pins that don't conflict.  For example you could use pins 2 and 3 to talk to the GPS and pin 6 to talk to the radio.

You are probably looking for plug-together package that is simpler than is actually possible, and may not be the best way go if it was.

The GPS can simply plug into the Uno but I haven't seen any version of the radio that will. If there was, it would need to be able to accept the GPS because the GPS would not be able to the Radio, i.e. the GPS is not stackable.

You would be better off looking at alternatives ways of using the products, such as a GPS shield with space for other components. Not the least would be making your own boards, either

1. one which has just the radio,  which plugs into the Uno and accepts the GPS board.

2. one which carries both the radio and a GPS module.

3. One which has both and also includes the MCU chip, thereby saving the maximum amount of weight, and keeping the Uno at home just for prototyping purposes.

Thank you so much for your answer! So is it possible to program the UNO in order to pick data from the GPS shield and transfer them using the ntx2? Sorry if it could be a simple thing, but I'm a rookie...  smiley-red

The example I saw of connecting the radio showed how to send text at 50 baud.  The GPS provides text.  It could be as easy as getting text from the GPS and forwarding that text to the radio.  If you want to get fancy you can add other sensors such as temperature, pressure, humidity, etc.
