Narrow Band Multi-Channel RF Transceiver Module
Product Description
The RC1240, RC1280 and RC1290 RF Transceiver Modules are compact surface-mounted
high performance modules for 25 kHz narrow band FSK operation with embedded protocol.
The modules are completely shielded and pre-certified for operation under the European and
US radio regulations for license-free use. When used with quarter-wave antennas a line-of-
sight range of 2-4 km can be achieved at 433 MHz.
