rfm12trx

A simple RFM12 433Mhz transceiver

Having the ability to easily facilitate radio links when tinkering with electronics is always a nice option. Using the relatively cheap RFM12 modules operating in the ISM band, any project can be equipped with a RF solution.

The rfm12trx acts as a bridge, connecting your control/measurement/automation software to your RFM12 enabled devices. All you need is a host where FT232R serial USB connections are supported, e.g. Windows, Linux, Raspberry Pi, …

The rfm12trx is a simple to use transceiver:
1. Hook it up to an USB port
2. Open a terminal, e.g. screen /dev/ttyUSB0 115200
3. Start sending/receiving hex data
4. Profit!
