Practical Application Scenarios
1. Smart Home Remote Appliance Control
By integrating the E160-R4FS1L (433.92MHz) into consumer electronics such as smart power strips, motorized curtains, and lighting fixtures, manufacturers can achieve reliable non-line-of-sight switching. The module's built-in 4-way GPIO output allows direct drive of relay circuits. Setting the digital pins to self-locking or interlocking mode simplifies hardware design, eliminating the need for an external microcontroller to manage state switching.
2. Secure Gate and Barrier Access Control Systems
The E160-R3FS1L (315MHz) is highly suited for gate barrier operators, rolling shutter doors, and garage access control. Supporting standard EV1527 learning code encoding, the module can store up to 15 unique key-fob transmitter addresses locally. Its high-performance superheterodyne architecture delivers superior anti-interference performance, ensuring prompt gate execution even in high-RF-noise suburban environments.
3. Light Electric Vehicle (LEV) and E-Bike Wireless Security
With its extremely small physical footprint of 20.4 x 11.3 x 3mm and ultra-low-power characteristics, the E160 series easily fits into the compact control enclosures of electric bicycles and scooters. Configured in momentary (jogging) output mode, the 4-way digital pins can handle arming, disarming, remote starting, and panic button triggers from handheld key fobs, ensuring robust wireless security integration.
FAQ Section
1. What is the key operational difference between E160-R3FS1L and E160-R4FS1L?
The primary difference is their target operating frequency band. The E160-R3FS1L operates at 315MHz, which is widely used in legacy automotive key fobs and older smart home systems. The E160-R4FS1L operates at 433.92MHz, which is the standard, highly robust ISM band globally accepted in Europe and the Americas for consumer remote control devices.
2. How do the three output modes (Momentary, Self-locking, Interlocking) function?
The 4-way GPIO pins can be hardware-configured into three control states: Momentary (outputs high level only while the transmitter button is held down), Self-locking (toggles the output level between high and low with each successive button press), and Interlocking (pressing one button sets its corresponding channel high while automatically resetting all other channels to low).
3. Does the module require an external MCU to pair with wireless key fobs?
No external microcontroller is required. The E160 series features an on-board hardware learning-button controller that natively decodes and registers EV1527 standard transmitter chips. It can directly memorize and store up to 15 different transmitter address groups inside its internal non-volatile memory.
