HXG-33A wireless data transmission module, open 433Mhz ISM band, license-exempt use, the use of the Nordic's high-performance nRF905 wireless communications chips. 

 HXG-33A upgraded version of its interface and code-compatible programming compatible with the RF905, longer distances, so you no longer worry about the distance. 

 [Applications] 

 Vehicle monitoring, remote control, telemetry, small wireless network, wireless meter reading, access control systems, residential paging, industrial data acquisition systems, wireless tags, identification, non-contact RF smart cards, small wireless data terminals, security, fire systems, wireless remote control system, bio-signal acquisition, hydrological and meteorological monitoring, robot control, wireless 232 data communications, wireless 485/422 data communications, digital audio, digital image transmission. 

 [Features] 
 (1) the 433Mhz to open ISM band is license-exempt use 
 (2) the maximum operating speed of 50kbps, efficient GFSK modulation, anti-jamming capability, built-in hardware CRC error detection, especially for industrial control applications 
 (3) the maximum transmit power: +33 dBm, the instantaneous current of the module maximum power to transmit signals <= 1A 
 (4) in the 3-meter configuration proprietary 15cm suction cup antenna open from the ground line of sight without interference Communications 2000 m. If the configuration of high-gain antenna, the communication distance can reach farther. 
 (5) modules in the transceiver mode switching time <1ms 
 (6) modules can be software based address, only to receive the address of the machine when the output data (interrupt instructions) can directly access a variety of microcontroller, software programming is very convenient 
 (7) TX Mode: +33 dBm, the average operating current less than 300mA; RX Mode: 12.5mA 
 (8) standard DIP spacing interfaces for the embedded application 

 (9) Operating voltage 5V and 3.3V 
 Interface definition] 

 The interface is a standard DIP pin spacing 100mil, 18 gauge double, if you need other package interfaces, such as fine-pitch pins, or other forms of interface, you can contact our custom.
