Powering creative minds
The worlds smallest (25% less volume than a 328 DIP chip alone), lowest cost (under £4 for bare board or £15 with SRF), RF capable (SRF or Hope RFM12B), Arduino IDE programmable device. Add 2 x AA and it'll blink! (on D13). 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 worlds 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 16Mhz, almost all of the Arduino pins are available for use (see 2nd picture).
Can be surface mounted making automated production now a reality or by using the supplied 2 x 10 way pin headers it can be plugged into xbee style interfaces/sockets. We already have sensor products that can with minor alteration also be used with this module. We will be delivering a whole range of solutions based around this module in the coming months.
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 suppport for conventional XBee/XRF type devices.
The chip antenna is great for space saving but for greatest range it can be simply snapped off revealing a pad that an 82.2mm wire will give an increase in range similar to an XRF.
Comes installed with the later smaller, faster Arduino UNO bootloader.
