DESCRIPTION

DRF4432D20I is a low-cost sub-1 GHz transceiver module designed for operations in the

unlicensed ISM (Industrial Scientific Medical) and LPRD bands. FSK (Frequency Shift Keying)

modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking

performance make DRF4432D20I modules easy to realize the robust and reliable wireless link.

The module can be configured to work in 40 channels with 1MHz channel space, which reduces

the interface from adjacent channels. It contains NetID and NodeID. Only modules with the same

NetID can communicate. The NodeID of modules can be different and it doesn’t affect the normal

use. The ID is reserved for the future network module.

DRF4432D20I integrates 256 bytes buffer. When the buffer is empty, users can transfer 200 bytes

data per time and even limitless data transfer can be achieved as long as RF data rate (RF module

to RF module) is configured to be faster than UART data rate (MCU to RF module). The module
