RPSMA antenna interface

Note

1, TTL, USB, RS232 Base Board

For the power of the output 1W power, XTEND must be used 5V power supply, current is close to 1A, and the line width of the single line of PCB is 40mil (1mm). Our TTL bottom board, the line to ensure 50*2=100mil (2.5mm), fully meet the requirements

2, Computer USB power supply

The use of PC or notebook USB power supply, only XTEND module configuration, 1W transmitter power can not be transmitted in the case of communications testing, because the general USB interface can only provide the maximum 500MA current

Xtend is very easy to use, and has the ultra long transmission distance, outdoor without occlusion case as far as you can reach 40 miles (lift), even in the room also can reach 3000 feet (900 meters) of transmission distance. Its work in the 900M ISM frequency band, with 115.2kbps data throughput, the module has a RPSMA antenna interface

XTend module uses FHSS (FM spread spectrum) technology to avoid interference and transmit power software adjustable (1mW-1W).
