Introducing SRX882 + STX882 433MHz ASK Wireless Receiver and Transmitter Module + Antenna  STX882 is an ASK transmitter module with a small size, ultra-high power, and 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, making wireless product development and production more convenient.

SRX882 is a superheterodyne receiver with a micropower, strong driving force, and a supplementary STX882 / STX888 module.
