EBYTE E160-RxFS1L Receiver Modules: E160-R3FS1L & E160-R4FS1L

Introduction: What Is the E160-RxFS1L Series Receiver?

In the wave of IoT and smart home, wireless remote control — thanks to its convenience, flexibility and low cost — is widely used in small appliance control, access control and toy remote control. At the heart of this wireless control is the wireless receiver module.

The E160-RxFS1L series from Chengdu EBYTE Electronic Technology Co., Ltd. is a low-power superheterodyne wireless receiver module with OOK/ASK modulation. It has two main models: E160-R3FS1L (315 MHz) and E160-R4FS1L (433.92 MHz). Both support EV1527 standard encoding and offer 4 independent output ports. With small size, wide voltage, low power and high stability, they are ideal for simple control applications.

Features & Model Comparison

Core Features

Small size — 20.4×11.3×3.0mm, ~3.65g, SMD/stamp-hole package with 2.54mm pin pitch, ideal for space-constrained applications.
Wide voltage & low power — 1.8~3.6V input, receive current 5~7mA, ideal for battery-powered remotes.
EV1527 encoding — recognizes 20-bit address and 4-bit key codes, compatible with most EV1527 transmitters.
Up to 15 address codes — pairs with 15 different remotes for multi-user/multi-device control; beyond 15, the oldest is overwritten.
4 independent level outputs — D0–D3 pins support momentary, latching and interlocking modes for various control logic.
Reference range — with the E160-TxFS1 transmitter, ~210m in clear open area, 1.5dBi antenna, 2m height.

Three Output Modes

Mode	LED blinks	Function	Typical application
Mode 1 [Latching]	2 (factory default)	each press toggles and holds the output level	lighting switch, power control
Mode 2 [Momentary]	3	high while held, low on release	access door, alarm trigger
Mode 3 [Interlocking]	4	pressing one channel sets it high, others low	electric curtain, roller shutter

Applications

Small Appliance Remote Control (fans, lighting)

Recommended: E160-R4FS1L (433.92 MHz, mainstream domestic band).
Integrate the E160-R4FS1L receiver with the E160-TxFS1 transmitter in fans and lighting for wireless on/off, speed and dimming control. Small size, low power and low cost suit mass production of home appliances.

Access Control Remote

Recommended: E160-R4FS1L or E160-R3FS1L (band per local regulations).
Install the E160-RxFS1L receiver in community gates, garage doors and office access systems for remote door opening. EV1527 encoding with up to 15 address codes enables multi-user pairing and high address uniqueness to prevent cloning.

Toy Remote Control

Recommended: E160-R4FS1L (433.92 MHz).
Integrate into remote cars, boats and planes for direction and speed control. The ultra-small size (20.4×11.3×3.0mm) and low power (<7.0mA) suit toy embedding and extend battery life.

Electric Bicycle

Recommended: E160-R4FS1L (433.92 MHz).
Integrate for remote alarm, one-touch unlock and remote start. The wide voltage (1.8~3.6V) runs directly from the e-bike battery, with high stability under vibration and temperature variation.

FAQ

Poor Transmission Distance

Line-of-sight obstacles attenuate distance.
Temperature, humidity and same-frequency interference raise packet loss.
Ground absorption/reflection reduces performance when testing near the ground.
Seawater strongly absorbs radio waves, so seaside tests degrade.
Metal near the antenna or a metal enclosure severely attenuates the signal.
Incorrect power register settings or overly high air data rate (higher rate = shorter distance).
Supply voltage below recommendation at room temperature lowers transmit power.
Poor antenna/module matching or antenna quality.

Module Easily Damaged

Check the supply stays within the recommended voltage; exceeding the maximum permanently damages the module.
Ensure stable power; avoid large frequent voltage fluctuations.
Use ESD-safe handling — high-frequency components are ESD-sensitive.
Keep humidity moderate during installation/use — some parts are humidity-sensitive.
Avoid extremely high/low temperatures unless necessary.
