Product Description

Cylindrical antenna (8CM, standard) whip antenna (21CM, optional) sucker antenna (multiple cable length optional)

Module Introduction:

RFC-33A long-distance wireless communication module using nRF905 wireless communications chips, superb performance, maximum transmit power of 2W (+ 33dBm), the maximum transmission distance of up to 3000 meters (open land), with superior penetration capability and high sensitivity (up to -100dBm), stable performance, high reliability, suitable for wireless communication, industrial remote control systems over long distances or complex cases and so on.

Performance and features:

(1) 433MHz ISM band license-free open use

(2) The maximum operating speed of 50kbps, efficient GFSK modulation, anti-interference ability, built-in hardwareCRC error detection, especially suitable for industrial control applications

(3) maximum transmit power: + 33dBm, the module with maximum power emission signal instantaneous current <= 900mA

(4) module switching time <1ms in receiving mode

(5) The module can be software set address, only received local address will output data (provide interrupt instructions), can be directly connected to a variety of MCU, software programming is very convenient

(6) TX Mode: at + 33dBm, the average current is less than 300mA; RX Mode: 12.5mA

(7) Standard DIP spacing interface, they can communicate with each other and RF905B, RF905SE, RF905RD, RFC-30F, RFC-30H modules.

(8) try to avoid high-power high-power transmitter module is a long time in the state! If you need to send data, it switches to receive mode or sleep mode.

(9) Since we offer a standard antenna (8.5cm long black rod antenna) optimum working frequencies in 440MHz to 450MHz, you can modify the carrier frequency to improve communication distance in this frequency range. In addition the company offers a variety of different antenna gain for selection.

(10) open to 3 meters above ground horizon undisturbed communication distance up to 2000-3000 meters; if you configure the high-gain antenna, the communication distance can reach farther.

(11) has a superior ability to penetrate indoor communications and complex environment is still a good communication effect

(12) PCB surface gold plating, high-quality device, more stable, more durable performance

(13) Module Size: 50mm * 30mm (without antenna size)
