5-Point Quick Selection Guide

Select by required transmission distance first. Choose E160-M series for general short-range remote control; choose E160-F series for medium-range applications; match E160-20 high-power transmitter with E160-D high-sensitivity receiver for long-range (up to 300m) scenarios.
Match frequency band strictly. Transmitter and receiver must use the same frequency band (315MHz or 433.92MHz) to work properly; 433MHz is recommended for global general use, 315MHz for regional specific requirements.
Choose data rate by application type. Select fixed low-rate F series for traditional fixed-code remote controls; select wide adjustable-rate M / 20 / D series for MCU-encoded smart remote and data transmission applications.
Evaluate power consumption for battery devices. For battery-powered remote controls and low-power sensors, select E160-M series receivers with 2.9mA ultra-low receive current to extend battery life.
Confirm package for integration. Standard stamp hole SMD packages are compatible with most PCB mass production; vertical DIP packages are suitable for through-hole soldering and prototype verification.

Frequently Asked Questions

Q1: What are the advantages of superheterodyne receivers over simple ASK receivers?

Superheterodyne architecture provides much higher receiving sensitivity, stronger anti-interference performance and more stable reception in complex environments. It can reliably receive weaker signals over longer distances, making it more suitable for industrial and security scenarios than simple ASK receivers.

Q2: Can I use a 315MHz transmitter with a 433MHz receiver?

No. Transmitter and receiver must operate at exactly the same frequency band to establish communication. Mismatched frequencies will result in no data reception at all.

Q3: What factors reduce the actual communication distance?

Obstacles such as walls, metal structures and trees will attenuate RF signals. Environmental electromagnetic interference, mismatched antennas, and insufficient supply voltage will also shorten the effective range. For best performance, use a matched antenna and install the module in an open position.

Q4: Do I need to program the module to use it?

E160 series modules work with simple GPIO data input/output. For basic remote control, you only need to connect data pins to your MCU or encoder chip; no complex firmware programming is required for the RF module itself.

Q5: Are E160 modules suitable for battery-powered products?

Yes. The E160-M series features ultra-low receive current (2.9mA) and low transmit current, making it well suited for battery-powered remote controls, wireless sensors and portable devices. For intermittent operation, you can further cut power consumption by powering off the module when idle.
