The VHF Radio Packet Modem (RPM1) is a low cost intelligent radio packet modem that enables a two way radio network/link to be simply implemented between a number of digital devices.
The TDM2 is a very simple 433MHz band radio data modem. It provides a medium ranged half duplex, transparent data link between a pair of 9600 baud RS232 ports without any additional interface circuitry
The DWA3 is a single channel, 869 or 915MHz wideband, transparent data link with a built-in ceramic patch antenna. It has a TDL2A pin-out (and firmware), but uses a BiM3 series radio module.
The I9600 is a 9600baud half-duplex serial modem controller suitable for use with wideband receivers, transmitters and transceivers. It takes care of preamble, synchronisation, bit balancing and error checking and enables a transparent radio data link to be established between radio devices.
The Narrow band Evaluation Kit (NBEK) IC can be used as 1200baud half-duplex serial modem suitable for narrow band receivers, transmitters and transceivers (or any RF modules with >5kbps data rate).
Available online in quantities of 1-10.
