Product Description
DC3V  No code 433MHz rf receiver module KL-RFM83L
DC3V No Code 433MHz RF Receiver Module Kl-Rfm83L

Series RFM83 and Series RFM83L are both low cost superheterodyne ASK/OOK receiver modules. There are two frequencies, 315MHz and 433MHz. (other frequency is customizable).

This module has stable performance, low power consumption, good sensitivity, and is very costeffective. It
can be widely used in various data transmission system.

It provides two extra PINs. PIN 1: Shut down PIN. Can shut down a part of circuit to make the receiver
standby when there is not signal input. PIN 2: Wake up PIN. It provides a output status indication when there is RF signal input.

It is a desirable choice when designing applications in field of wireless transmission. RFM83
adopts DC 5V as input voltage while RFMS83L adopts DC 3V.

1. Characteristic:

Ø  High sensitivity, -108dBm.

Ø  Small size (32*11*4.3mm).

Ø  Low power consumption.

Ø  Low self emission, can easy pass all kinds of certification.


2. Specification:

Ø  Frequency: 433/315MHz

Ø  Working Voltage: DC 2.7-3.6V, optional

Ø  Working Current: 4mA

Ø  Modulation: ASK/OOK

Ø  Working Temperature: -10~70°C


3. Applications:

1). Garage door and gate openers

2). Electric windows, barrier, etc.

3). Remote controls and smart home alarm

4). Low baud rate for data transmission

5. Matching Transmitter:
1. Match code: 
When the receiver module is powered, hold the learning button and the LED indicator blinks, then press any button of remote control or power a transmitter module to launch, if indicator flashes 3 times, match code successfully. Maximum 20 remote controls / transmitter modules can be matched.

2. Delete code:
Hold learning button till the indicator LED lights and then off, delete successfully.

3. Set working mode:
S1 & S2 program the sequence as follows:
S1 Short Circuit→ Toggle
S2 Short Circuit→ Latching
S1 & S2 both not short→ Momentary

6. Short Introduction of Working Modes
The following introduction will describe how momentary, latching and toggle working using example of typical two channel receiver. The transmitter button A controls channel 1 while transmitter button B controls channel 2.

1. Toggle - Press A > Channel 1 ON and remains ON, Press A again > Channel 1 OFF
2. Momentary - Press and hold A > Channel 1 ON, Release A > Channel 1 OFF
3. Latching - Press A > Channel 1 ON and remains ON while Channel 2 OFF, Press B > Channel 2 ON and remains ON while Channel 1 OFF

5. Shipping
