SRWF-1101, the low-power wireless transceiver data module

Technical specification of SRWF-1101: 1. Transmit power is 50mw. 2. Transmit distance is 150m in-building range, 700m in open ground. 3. Center frequency is 433MHZ / 315MHZ / 868MHZ. 4. We have three Interface mode : UART TTL / RS-232 / RS-485, but you can only choose one of it when you buy it. 5. We use GFSK/FSK Modulation mode and use the high- efficiency forward error correction channel encoding technology so our modules have High anti- interference and low BER(Bit error Rate) feature. 6.The standard SRWF-1101 configuration provides 8 channels. If the user needs, it can be extended to 16/32 channels, meeting the multiple communication combination mode of the user. 7.Interface baud rate is 9600bps with format of 8N1/8E1 and user self- definition, allowing the transmission of long data frames at one time for more flexible programming by users. (If the user needs, it can also transmit the data in unlimited length at one time). 8.Even for semi duplex communication, the user doesn't need to prepare excessive programs, only receiving/transmitting the data from the interface. SRWF-1101 will automatically, complete the other operations, such as transmission/receiving conversion in the air, control, etc.
