VIBRATION RX521

RX521 is an ASK receiver module operating at 315MHz/433.92MHz. The module features high sensitivity (−112dBm), low power consumption (<5.5mA), and wide dynamic range (>80dB), along with strong anti-interference performance. Designed around the highly integrated Vi521R chip, the module incorporates a built-in LNA, mixer, filter, PLL, and voltage regulator, delivering stable and reliable performance. The RX521 operates over a supply voltage range of 2.5~5.5V, with a typical operating current of 5.0–5.2mA and a maximum receive sensitivity of −112dBm. The module dimensions are 23.7mm × 8.2mm.
