RFM12B-868-S2

RFM12B-868-S2
Wireless Transceiver ISM 868MHz, FSK SPI, SMD

The RFM12B is an ISM band FSK transceiver module implemented with a unique PLL. These modules operate in the 868MHZ band and fully comply with FCC and ETSI regulations.

SPI interface is used to send data and configure the RFM12 module. The configuration commands, described in the RF12 IC Datasheet linked below, can be used to set the data rate, frequency band, wake-up timer, transfer data, receive data from the 16-bit FIFO, and much more.

The module comes in a 14-pin SMD package, with pins spaced by 2mm.

Key Features:

• Fully integrated (low BOM, easy design-in)
• High bit rate (up to 115.2 kbps in digital mode)
• Direct differential antenna input/output
• Integrated power amplifier
• Automatic frequency control (AFC)
• Data quality detection (DQD)
• SPI compatible serial control interface
• 16 bit RX Data FIFO
• Two 8 bit TX data registers
• Low power duty cycle mode
• 2.2 to 3.8 V supply voltage
• Low power consumption
• Low standby current (0.3µA)
• Supports very short packets (down to 3 bytes)
• Dimensions: 15.9 x 16.1 mm
