The 433MHz 100 Meters STX882 ASK Transmitter Module is a compact, cost-effective wireless RF transmitter module designed for short to medium-range unidirectional wireless data communication.
The 433MHz 100 Meters STX882 ASK Transmitter Module is a compact, cost-effective wireless RF transmitter module designed for short to medium-range unidirectional wireless data communication. Built around high-stability surface-mount components and SAW resonator technology, this module operates at the widely used 433.92MHz ISM frequency band with low harmonic radiation and strong anti-interference performance.
Working on Amplitude Shift Keying / On-Off Keying (ASK/OOK) modulation, the STX882 features a wide operating voltage range (2.0V to 5.5V DC) and delivers higher RF output power at higher supply voltages, enabling transmission distances up to 100 meters in open field conditions when paired with a matching antenna and receiver (such as SRX882).
This module is widely used in wireless doorbells, remote keyless entry, garage door openers, smart home automation switches, and wireless sensor nodes. It features a minimal 3-pin interface (ANT, DATA, VCC, GND), making it extremely easy to interface with microcontrollers like Arduino, ESP32, ESP8266, STM32, PIC, and general DIY electronics.
