RFM12B Board (v1)
The RFM12B Board is a compact breakout board for HopeRF's RFM12B radio module.
The board works with a whole range of Arduino (compatible) boards. For ease of use, the header pins are labeled with signal names as well as Arduino pin numbers.
The RFM12B radio module supports a power supply level of up to 3.8V. To be able to use the RFM12B in a 5V context, this board features a voltage regulator circuit and voltage level converters for signal pins, besides pads for the RFM12B module itself. For use with 3.3V, the regulator and level conversion components can be left out.
An antenna must be connected to the module - for 868 MHz, an 82-mm long piece of wire can be used (quarter wavelength).
See the RF12 library for source code and examples.
Configuration
When used at 5V, all components should be included. At 3.3V, they can be omitted and the 3 solder jumpers closed instead.
