PEASE NOTE: RFu shaped has changed. Please see product photos for more detail.
IMPORTANT ADVICE: If you haven't used an RFu before, and want to go prototyping, you will find it very useful to have one of these RFu developer board
The RFu-328 is the world’s smallest, most affordable, RF capable, over the air Arduino IDE programmable device:
Aimed at making Arduino powered products a reality. Ideal for lower power or smaller size projects and even small scale product production, this tiny module is perfect for the new age of the Internet of Things. The module has an SRF radio module installed so it's an out the box low power RF node. It's the world’s only SOM (system on module) Arduino device that can be programmed over the air direct from the Arduino IDE.
Will run the same code as the larger XinoRF because it shares the same ATmega 328 micro running at 16 MHz, almost all of the Arduino pins are available for use. So you can develop your system with the XinoRF and deploy with RFu-328.
Also available without the SRF, so you can mount your own RFM12B unit (RFU-328-BARE).

Arduino Board Type: Arduino Uno
Dimensions: 2.53mm x 22mm x 27.70mm (or 35.5mm long with chip antenna)
Default Baud Rate - The SRF Radio on the RFµ-328 has a default baud rate of 115200
OTAMP Default Settings
The RFµ-328 is pre configured for OTAMP with the following settings:
If you wish to program with an FTDI style interface you will need to put a 0.1uf capacitor between the interface DTR and pin 5 (RESET) this is the same technique employed on the Arduino, this gives your interface the ability to auto reset the module which is required to invoke the Arduino bootloader. Alternatively look at our new 4 in 1 Explorer Plus USB interface which has an XBee style socket, FTDI style connector and built in SRF-U which has an RFu Auto Reset enable jumper as well as support for conventional XBee/XRF type devices.
