433MHz RF Communication Module Wireless Transceiver Board 100mW SPI Interface RF4432PRO

Introduction: The RF4432PRO module uses the Silicon Lab Si4432 device, a highly integrated wireless ISM band transceiver chip. Extremely low receive sensitivity (-121dBm) combined with industry-leading +20dBm output power, ensures extended range and improved link performance. At the same time, built-in antenna diversity and support for frequency hopping can be used to further expand the range and improve performance. Feature: Frequency range: 433/868 (can be customized 240-930MHZ) Sensitivity up to -121dBm Maximum output power: 20dBm 30mA@+13dBm (emission) Data transfer rate: 0.123-256kbps FSK, GFSK and OOK modulation modes Ultra low power shutdown mode Digital Received Signal Strength Indication (RSSI) Timed wake up function Antenna automatic matching and bidirectional switch control Configurable packet structure Preamble detection 64-byte Transceiver Data Register (FIFO) Low power detection Integrated voltage regulator Frequency hopping function 1.8-3.6 V power supply Operating temperature range: -40 ~ +85 C Weight: 1.2 g 1.8-3.6 V power supply Application: remote control Remote meter reading industrial control Home automation telemetry Toy control Wireless PC peripheral Tag reader Parameter Min.
