Ruth's sister 433 MHz Superheterodyne Receiver Module internal power cable

SKU CH-V3CJ-5HVDY

A 433.92 MHz superheterodyne receiver module with up to -110 dBm sensitivity and 3 V to 5.5 V supply range

  • High-sensitivity reception down to -110 dBm for reliable wireless links
  • Superheterodyne architecture rejects interference from multiple nearby modules
  • Ultra-low 50 nA power-enable current extends battery life
  • Wide 3 V to 5.5 V supply range suits 3.3 V and 5 V logic
  • Industrial -40 °C to 85 °C operation withstands harsh environments

433.92 MHz Superheterodyne Receiver

This 433.92 MHz superheterodyne receiver module suits engineers and hobbyists building wireless control systems. It operates from a 3 V to 5.5 V supply and draws 6.0 mA at 3.3 V. The RXB6 design provides sensitivity up to -110 dBm for reliable data capture in remote door, alarm or curtain applications.

Compact board with analog RSSI output

Measuring 4.2x2 mm the module fits tight enclosures and can run multiple units side by side without mutual interference. An analog RSSI signal strength output lets firmware monitor link quality. Power-enable mode drops consumption to 50 nA extending battery life in portable sensors.

Industrial temperature range -40 to 85

Rated from -40 to 85 the board withstands harsh ambient conditions found in automotive or outdoor installations. No certification is declared so compliance testing remains the integrator responsibility. Single-piece quantity supports prototyping before volume orders.

Questions about this item

What frequency does the 433.92 MHz superheterodyne receiver operate on?

The module operates at a fixed frequency of 433.92 MHz, which is the standard ISM band used for remote controls, wireless sensors, and data links in Europe and many other regions.

What voltage range and current draw does the RXB6 module require?

It accepts a supply voltage from 3 V to 5.5 V and typically draws 6.0 mA at 3.3 V, with a power-enable mode that can reduce consumption to as low as 50 nA.

How should the RSSI output pin be connected for signal-strength monitoring?

The analog RSSI pin provides a voltage proportional to received signal strength; connect it to an ADC input on your microcontroller and read the level to gauge link quality or trigger wake-up logic.
