 Brief introduction

RFM22B /RFM23B are highly integrated, low cost,433/868/915MHZ wireless ISM transceivers module. The low receive sensitivity(–121dBm) coupled with industry leading +20dBm/ +13dBm output power ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping can be used to further extend range and enhance performance.  Additional system features such as an automatic wake-up timer, low battery detector, 64 byte TX/RX FIFOs, automatic packet handling, and preamble detection reduce overall current consumption and allow the use of lower-cost system MCUs. An integrated temperature sensor, general purpose ADC, power-on-reset (POR), and GPIOs further reduce overall system cost and size.
