Introduction
RX831E is an ASK receiver module operating at 315MHz/433.92MHz. The module features high sensitivity (-113dBm), low power consumption (<5.5mA), high dynamic range (>90dB), and excellent anti-interference performance. Designed around the highly integrated VT831R chip, the module incorporates a built-in LNA, mixer, filter, PLL, and voltage regulator, delivering stable and reliable performance.
The RX831E operates over a supply voltage range of 2.5–5.5V, with a normal operating current of 5.0–5.3mA, a startup time of 3.6ms, and a maximum receive sensitivity of -113dBm. The module supports a PD function that reduces average operating current through intermittent operation. The startup time after the PD signal transitions from high to low is 3ms, making it particularly suitable for applications with ultra-low power consumption requirements. The module dimensions are 23.7mm × 8.2mm.
