This is 433MHz 100 Meters STX882 ASK Transmitter Module + SRX882 Superheterodyne Receiver Module + Antenna.

STX882 is an ASK transmitter module with small size, ultra-high power, low harmonics. With high stability, it is achievable at 50mW power when the voltage is 3.6V, it is the maximum transmitter power module under the same voltage in the market. The data port of the module can be connected to the microcontroller directly, make wireless product development and production more convenient.

SRX882 is a superheterodyne receiver with a micropower and strong driving force, which is a supplementary STX882 / STX888 module. The data port of the module can be connected to the microcontroller directly, make wireless product development and production more convenient.
