Part Name Overview
RF Frequency band Typ output power VCC / VCC_PA
Typical application circuit:
Note that the VCC_PA pin supply the internal power amplifier only, while the rest of the
internal block runs on VCC. They can be connected together (max 3.6V) or separated using
individual supply. If VCC_PA is connected together with VCC, the max output power is +24
How do I transmit data?
Send your data to the RXD pin on the module. Use the UART format with settings (19200, 8,
1, N, no flow control). Up to 12 bytes payload are buffered in the module. The first byte of the
message must contain the message length (excluding the length byte itself). The module will
transmit the data when the whole packet is received.
How do I receive data?
The module has to be configured to “Uplink and downlink” mode in order to enable two way
communication. Any received RF data packet with correct message format (ID, key, CRC) will
be sent on the TXD pin with length byte first. The RSSI value (received signal strength) can
optionally be added to the message.
What about the antenna?
In most cases a simple quarter wavelength wire or a PCB track will do. Connect a piece of
wire to the RF pin with length corresponding to the quarter of a wavelength. For space limited
products, contact Radiocrafts and we will recommend the best antenna solution for your
How do I change any configuration parameter?
To change configurable parameters, send one byte to the module with the value 0x00 or
assert the CONFIG pin. This will take the module into configuration mode. Special commands
are then used to access the configuration registers and test modes. Exit from configuration
mode by sending the ‘X’ command. Parameters can be changed permanently and stored in
non-volatile memory in the module.
