The FRPC2 is a self-contained plug-on radio port which requires only a simple antenna, 5V supply and

a byte-wide I/O port on a host microcontroller (or bi-directional PC port).

The module provides all the RF circuits and processor intensive low level packet formatting and packet

recovery functions required to inter-connect an number of microcontrollers in a radio network.

A data packet of 1 to 60 bytes downloaded by a Host microcontroller into the FRPC2's packet buffer is

transmitted by the FRPC2’s transceiver and will "appear" in the receive buffer of all the FRPC2's within

radio range.

A data packet received by the FRPC2’s transceiver is decoded, stored in a packet buffer and the Host

microcontroller signalled that a valid packet is waiting to be uploaded.

Modules: FRPC2-433-160: IC+BiM2-433-160

IC’s:

FRPC-000-DIL:

18 pin DIL IC

FRPC-000-SO:

18 pin SO IC

The RPC2-433-160 is intelligent transceiver

modules, which enable a radio network/link to

be simply implemented between a number of

digital devices. The module combines a UHF

radio transceiver and a 160kbps packet

controller.
