RFM12B-SP Wireless Transceiver Regulated

The RFM12B is a great inexpensive option for wireless communication; it's an ISM band FSK transceiver module implemented with a unique PLL. These modules operate in the 434MHZ band.

This new version of our breakout board now includes a 3.3V Voltage Regulator, plus Logic Level Conversion circuitry so you you can connect it directly to 5V systems.

This module has a voltage supply range of 3.5V - 6V DC. An 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.

There is great support for this module, with libraries and example code available for Arduino and AVR.

Board Size: 25.4mm x 19mm (1.00 in x 0.75 in)

Features:

  • On-board 3.3V Voltage Regulator
  • Logic Level Conversion
  • Suitable for direct connection to both 3.3V and 5V systems
  • Up to 300m transmission
  • Up to 115Kbps
  • Up to 28 nodes per network
  • Up to 250 different network groups
  • Low-cost, high-performance
  • SPI compatible interface
  • 3.5V - 6V power supply
  • Automatic antenna tuning
  • 16-bit RX data FIFO

Antenna sizes at 434MHz should be made as follows

  • 1/4 wave = 164.7mm
  • 1/2 wave = 329.4mm
  • full wave = 692.7mm
