The RX – ASK is an ASK Hybrid receiver module. It is a effective low cost 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 cost, small size and simple to use for designing.

Please note 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.
