Replacement:WRL-10153. This has been replaced with the RFM22B. We will no longer be carrying this product and this page is for reference only.
The RFM22 is a low-cost ISM FSK transceiver module which offers communication at 434MHz and adjustable output power of up to +17 dBm. The wide operating voltage range of 1.8–3.6 V and low current consumption makes the RFM22 an ideal solution for battery powered applications.
Communication with the RFM22 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: We found these in inventory and they work fine but we’re no longer stocking them. We’ll be selling them at a discount for a limited time but when they’re gone, they’re gone!
