## Description

433MHz wireless transceiver set for commands and telemetry, ideal for Arduino and automation projects. Offers stable communication up to 100 m, high transmission power up to 50 mW at 3.6 V, high sensitivity for reliable reception and low consumption, includes two helical antennas for quick installation and better signal.
The transmitter and receiver module set, STX882 and SRX882, is a wireless control device with small size, high power and low harmonics, which can reach a communication distance of up to 100 meters. It can reach a power of 50mW at a voltage of 3.6V, being among the most powerful transmission/reception modules at this voltage. Direct connection with microcontrollers facilitates the development and production of wireless devices, being compatible with Arduino and other development boards.
The SRX882 ASK receiver module is a superheterodyne receiver with low power consumption and high drive force.
The 433MHz transceiver kit includes an ASK STX882 transmitter module and an SRX882 receiver, plus two helical antennas.
