Robomart 434 MHz 4 ch. RF Wireless Robotic Board V2

The Device is a pair of two modules - a transmitter and a receiver. Together they make an addressable wireless system that can range up to 65 meters. The RF Modules used is compatible to HT12D / 12E standards.Transmitter End:Transmitter of wireless remote is a powerful transmitter module based on CMOS technology. There is internal calibrated crystal oscillator in module IC HT12E, so there is no need to provide crystal oscillator externally.This module have 18 pin encoder IC ( HT12E ) , with which the 4 pin female connector compatible with 12D RF transmitter antenna is connected and one 8 Bit Address select is connected . 8 Bit address select gives us the option of isolating the communication between the transmitter and the receiver module. 4 Bit Data is available for providing Input to the Encoder IC. On board we have one L 7805 voltage regulator that regulates the voltage ranging from 5 V ~ 24 V.Receiver End:Receiver of wireless remote is a powerful transmitter module based on CMOS technology. There is internal calibrated crystal oscillator in module IC HT12D, so there is no need to provide crystal oscillator externally.This module has 18 pin decoder IC ( HT12D ) , with which 8 pin female connector compatible with 12D RF receiver antenna is connected and 8 Bit Address select is connected . 8 Bit address select gives us the option of isolating the communication between the transmitter and the receiver module. 4 Bit data pins are given for data Output. One LED is connected to denote valid transmission. On board we have DTMF decoder IC add - on Shield for interfacing DTMF decoder IC module. On board we have one L 7805 voltage regulator that regulates the voltage ranging from 5 V ~ 24 V.
