Product description:

The RFM12B transceiver module is a complete RF receiver and transmitter, suited for exchanging data with a data rate up to 115.2 kbit/s. The transceiver module is an efficient receiver with a high sensitivity and an efficient transmitter with high ouput power. Because of the SMD construction, the module has a very small shape.
The transceiver can be controlled directly by a microcontroller with SPI interface. This way the total hardware of the system can be limited to a minimum.

The module is available for the 433 MHz en 868 MHz ISM frequency bands used in Europe.
The module comes in six different packages: DIL, SMD1 en SMD2 and in every package the option for DIE or TSSOP (suffix: P).
There is no difference between the DIE and TSSOP version other than the TSSOP package is better suited for Reflow manufacturing.
The S1 package in TSSOP (Suffix:P) is normal stock.

* under specific conditions:
The range depends on the following parameters:
- TX power
- RX sensitivity
- Data rate
- Transmitter bandwidth
- Receiver bandwidth
- Antenna height
- Antenna type
- Radio protocol
- Etc.

Snelle levering en leuke modules. Ik werk er al jaren mee in combinatie met Microchip als microcontroller. Geen reden om voor een andere module te kiezen.

Perfecte kleine module. Makkelijk aan te sturen met adruino. Ik gebruik hiervoor de Jeelib library.
Jammer dat de verzendstatus niet te volgens is. Verder alle wel prima ontvangen.
