Main Features

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.
Frequency range: 433MHz
Power supply: 1.8-3.6 V
Operating temperature range: -40 ~ 85 °C
Sensitivity: up to -121dBm
Maximum output power: 20dBm (30mA@ 13dBm)
Data transfer rate: 0.123-256kbps (FSK, GFSK, OOK mode)
- 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
