Introduction

STX885 is a highly integrated, low-cost ASK transmitter module with built-in encoding, featuring an ev1527 digital encoding circuit, high-precision oscillator, and power amplifier. The module supports two operating frequencies: 315MHz and 433.92MHz. The integrated high-precision oscillator provides accurate pulse width timing; the dual encoding format design reduces code collision rates and supports multi-key composite codes to prevent accidental triggering of special keys. The STX885 features compact size, low harmonic emissions, and high stability, making it suitable for a wide range of wireless remote control systems. The STX885 is manufactured and tested using a strict lead-free process, compliant with RoHS and REACH standards.
