- Ready for car remotes, alarms and curtains
- Superheterodyne design rejects interference between multiple receivers
- 0 mA draw at 3.3 V extends battery life
- Works from -40 °C to 85 °C in harsh environments
- Up to -110 dBm sensitivity captures weak signals
433 MHz wireless link kit
The kit pairs a superheterodyne receiver module with a small transmitting module for 433.92 MHz wireless control. It suits hobbyists and engineers adding remote switching to alarms, curtains, garage doors or industrial controllers. The receiver draws 6.0 mA at 3.3 V and can drop to 50 nA in power-enable mode. An analog RSSI output lets you monitor link quality.
Replaces basic ASK or OOK modules
The superheterodyne architecture gives sensitivity up to -110 dBm and strong spurious suppression, so multiple receivers can operate side by side without mutual interference. Upgrade when simple ASK boards suffer from false triggers or limited range in noisy environments. The wide 3 V to 5.5 V supply range eases integration into existing 3.3 V or 5 V logic without extra regulators.
Check antenna layout and supply rails
Verify your PCB has space for the 4.2 x 2 mm receiver footprint and a suitable 433 MHz antenna trace or whip. Ensure the host can supply a clean 3.3 V to 5.5 V rail at the stated current and that the analog RSSI pin connects to an ADC input if signal monitoring is needed. The module is rated for -40 to 85 °C operation, so confirm the enclosure ambient stays within that window.

Questions about this item
What are the physical dimensions of the RXB6 receiver module?
The RXB6 receiver module measures 4.2 by 2 millimetres, making it compact for integration into small enclosures.
How do I wire the RXB6 module to a 3.3 V power supply correctly?
Connect VCC to a 3 V–5.5 V source and GND to ground; the module draws 6.0 mA at 3.3 V and must not exceed 5.5 V.
What is the expected operating temperature range for the RXB6 module?
The module operates from -40 °C to 85 °C, so it remains functional in harsh ambient conditions.
