Description
Item Overview: The RF4432X1 module uses the Silicon Lab Si4432 device, a highly integrated wireless ISM band transceiver chip. Extremely low receive sensitivity (-121 dBm), combined with industry-leading output power of 20 dBm, guarantees 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. Specifications: Frequency range: 433MHzPower supply: 1.8-3.6 VOperating temperature range: -40 ~ 85 °CSensitivity: up to -121dBmMaximum output power: 20dBm (30mA@ 13dBm)Data transfer rate: 0.123-256kbps (FSK, GFSK, OOK mode) Features: - Ultra low power shutdown mode and digital receive signal strength indicator (RSSI)- With timer wake-up function, frequency hopping function, power-on reset function and built-in crystal adjustment function- Antenna automatic matching and bidirectional switch control- configurable packet structure- 64-byte Transceiver Data Register (FIFO)- Low energy detection and pre-sync signal detection and temperature sensing- with 8-bit analog-to-digital converter and integrated voltage regulator Technical Parameters:ParameterMinimumTypicalmaximumUnitConditionOperating conditionsOperating Voltage1.83.33.6V Operating temperature-40 85?
