DRF1212D10 is a type of highly integrated and extra low power consumption transceiver module based on SX1212 RFIC. Innovative coding technology EDAC (looped interleaving Error Detection and correction) is utilized to assure reliable communication and achieve longer distance comparing to other common coding technology. It consumes less than 3mA current in normal receive mode. With low working voltage it is very suitable for hand-held wireless applications.

The module can be configured to work in different channels with 200 KHz space. It adopts high efficient looped interleaving EDAC (Error Detection and correction) coding with coding gain up to 3dB which keeps in advance in error correction and coding efficiency over normal FEC (Forward Error Correction) coding. Because of its high reliability in correction, modules can filter error and fake information automatically and realize truly transparent wireless link, which makes DRF1212D10 very suitable in the rigid communication environment.
DRF1212D10 integrates two 256 bytes buffer. When the buffer is empty, users can transfer 256 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). DRF1212D10 provides standard UART/TTL interface for selection. Users can choose seven data rates and three parity checks which make DRF1212D10 possibly tailor-made for different applications. DRF1212D10 operates at 2.1~3.6V with extra low power consumption. The current in polling mode can be minimized to 20uA and the current in receive mode no more than 4mA makes modules very suitable for battery powered-up applications.
