SKU RFM22B-S2-86
The RFM22B is a low-cost ISM FSK transceiver module which offers communication at 868MHz ISM bands 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.
