The BiM1 is a half duplex radio transceiver module for use in long range bi-directional data transfer applications at ranges up to 10kilometres. The module
operates on the UK licence exempt frequency of 173.225/173.250MHz with 10mW RF output.
The small footprint of 23 x 33mm and low profile of 10mm together with low power requirements of <80mA (for 100mW) at 3.8V enable convenient PCB installation.
BiM1 is also available as separate BiM1T transmitter and BiM1R receiver which can be used as dual-in-line equivalents of TX1 transmitter and RX1 receiver
The BiM2 is a half duplex radio transceiver module for use in high-speed bi-directional data transfer applications at ranges up to 200 meters.
The module operates on the European licence exempt frequency of 433.92MHz and conforms to the relevant sections of EN 300 220-3 and EN
The small footprint of 23 x 33mm and low profile of 4mm together with low power requirements of <20mA @ 3 to 5 Volts enable convenient PCB
installation. The high raw data rate capability of 64kbit/s and fast state change times will support high data throughput in streaming
applications or alternatively allows very short air time utilization (TX on < 10 ms) in multi-node scanning networks.
The BiM3A suited to battery-powered portable and handheld equipment requiring a high degree of miniaturisation. Two frequency variants are available as
standad to suit applications in Europe or North America.
The SP2 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 interconnect an number of microcontrollers in a radio network.
A data packet of 1 to 60bytes downloaded by a Host microcontroller into the SP2's packet buffer is transmitted by the SP2's transceiver and
will "appear" in the receive buffer of all the SP2's within radio range.
A data packet received by the SP2's transceiver is decoded, stored in a packet buffer and the Host microcontroller signaled that a valid packet
is waiting to be uploaded.
