Radio and testing

Once the bootloader is burned on the 328p MCU, the board is ready to accept user sketches straight from the Arduino IDE or even through the command line via avrdudess/avrdude.

Here we illustrate how to solder an RFM69HW module.

Notice the orientation of the module before soldering, this is very important, soldering it wrong will render the module non-functional!

You may also add theĀ W25X40CLSNIG 4MBIT FLASH-MEM chip (datasheet), this is useful if you plan to try wireless (OTA) programming, or want to use it as extra memory (like a small hard drive for your Moteino!).

To test the radio module, you will need another Moteino or a different board with an RFM69 radio – at least two are needed to make a communication link. Once ready, you can look at the many examples in the RFM69 library. For basic testing or a radio link you can use the Node and Gateway examples, or the TxRxBlinky example which can be used on both the sender and receiver units, along with a button for user interaction.
