RFM69CW 433MHz Wireless Transceiver Breakout

The RFM69CW is a pin-compatible upgrade to the polular RFM12B radios and offers improved sensitivity and range compared (+30%) at the cost of a small increase in power consumption. The new module also supports RSSI which is a useful addition.

We have created this breakout board to make connecting to this module very easy. The breakout board includes a 3.3V Voltage Regulator, plus Logic Level Conversion circuitry so you you can connect it directly to 5V systems.

The module 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 and fully comply with FCC and ETSI regulations.

This module has a wide voltage supply range of 2.2-3.8VDC. An SPI interface is used to send data and configure the RFM69CW module. The configuration commands, described in the RFM69CW 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

Arduino Library

There is an excellent RFM69CW Arduino Library available from LowPowerLabs. However, their example code is intended for their own boards which include a Flash RAM chip. This code needs removing in order to work correctly, so we have included the two example programs for Node and Gateway below which we have modified to work.

Features:

  • 3.3V - 6V supply
  • Logic level conversion
  • Direct connection to both 5V and 3.3V systems
  • +13 dBm Power Output Capability
  • Operates on 433MHz unlicensed ISM band
  • Built in AES-128 encryption and CRC-16 engine
  • FSK Bit rates up to 300 kb/s
  • High Sensitivity: down to -120 dBm at 1.2 kbps
  • Packet engine with 66-byte FIFO
  • Built-in temperature sensor
  • Line-of-sight ranges in excess of 1km
  • High Selectivity: 16-tap FIR Channel Filter
  • Bullet-proof front end: IIP3 = -18 dBm, IIP2 = +35 dBm,80 dB Blocking Immunity, no Image Frequency response
  • Low current: Rx = 16 mA, 100nA register retention
  • Programmable Pout: -18 to +13 dBm in 1dB steps
  • Fully integrated synthesizer with a resolution of 61 Hz
  • FSK, GFSK, MSK, GMSK and OOK modulations
  • Built-in Bit Synchronizer performing Clock Recovery
  • Incoming Sync Word Recognition
  • 115 dB+ Dynamic Range RSSI
  • Automatic RF Sense with ultra-fast AFC
  • Module Size:16X16mm
