The RX - ASK is an ASK Hybrid receiver module. It is a effective low rate solution for using 433 MHz. The TX-ASK is an ASK hybrid transmitter module. TX-ASK is designed by the saw resonator, with an effective low rate , small size and simple to use for designing. Please know that this device will not support direct UART communication when connected to PC or microcontrollers as there is a lot of noise always available on these frequencies. If you are looking for Serial Communication see RF 2.4Ghz Serial Link instead of this product. We will not be providing any support for serial communications after sales. For remote control applications please use Encoder and Decoder ICs. Features Range in open space(Standard Conditions) : 100 Meters RX Receiver Frequency : 433 MHz RX Typical Sensitivity : 105 Dbm RX Supply Current : 3.5 mA RX IF Frequency : 1MHz Low Power Consumption Easy for Application RX Operating Voltage : 5V TX Frequency Range : 433.92 MHz TX Supply Voltage : 3V ~ 6V TX Out Put Power : 4 ~ 12 Dbm.
