RFM12B 868 MHz
- Vendor: HopeRF
- Type: Components
The RFM12B radio module by HopeRF is a small wireless radio module for sending and receiving packets on the 868 MHz ISM band using FSK.
This module is used by all JeeNodes and JeeLinks. It can be controlled via the SPI bus, and works with a power supply level of up to 3.8 V.
An antenna must be connected to the module – for 868 MHz, an 82-mm piece of wire can be used (quarter wavelength).
For the specifications, see HopeRF’s RFM12B page. For details on how to hook it up and an Arduino library with sample C code, see this post on the JeeLabs daily weblog.
For a breakout board for this module and a 5V option, see the RFM12B Board.
