RFM22B-S2 SMD Wireless Transceiver

10 €10.00

Availability: Retired

The RFM22B is a low-cost ISM FSK transceiver module which offers communication at 433MHz ISM and adjustable output power of up to +20 dBm. The wide operating voltage range of 1.8–3.6 V and low current consumption makes the RFM22B an ideal solution for battery powered applications.

Communication with the RFM22B is achieved via a standard 4-wire SPI interface. Three configurable general purpose I/Os are also available, the use of which can be tailored towards the needs of your project. A host of other features are also available including an 8-bit ADC, temperature sensor, RX and TX FIFOs, and low-battery detection. See the datasheet below for a complete description of every register and command.

The module comes in a 16-pin, 16 x 16mm, SMD package, with pins spaced by 2mm. Look for a breakout board coming soon!

Note: These modules are 433MHz and Rev3.0.

Features:

  • Frequency Range: 433MHz ISM
  • Sensitivity = -121 dBm
  • Output power range: +20 dBm Max
  • Data Rate = 0.123 to 256 kbps
  • FSK, GFSK, and OOK modulation
  • Power Supply = 1.8 to 3.6 V
  • Ultra low power shutdown mode
  • Digital RSSI
  • Wake-up timer
  • Auto-frequency calibration (AFC)
  • Power-on-reset (POR)
  • Antenna diversity and TR switch control
  • Configurable packet handler
  • Preamble detector
  • TX and RX 64 byte FIFOs
  • Low battery detector
  • Temperature sensor and 8-bit ADC
  • –40 to +85 °C temperature range
  • Integrated voltage regulators
  • Frequency hopping capability
  • On-chip crystal tuning

Dimensions: 16 x 16mm (0.63 x 0.63 in)
