The **JR-00-R** typically refers to a specific series of **RF (Radio Frequency) Remote Control Receiver Modules**, often used in consumer electronics for wireless signal processing (such as ceiling fans, light controllers, or motorized gates). Below is a breakdown of the electronic components and technical specifications associated with these types of modules. --- ### 1. Core Component Breakdown | Component Type | Function | Common Parts Used | | :--- | :--- | :--- | | **RF IC / Decoder** | Decodes the incoming wireless signal from the transmitter. | EV1527, PT2272, or MCU-based | | **Antenna** | A coiled wire or PCB trace designed to capture 315MHz or 433MHz signals. | Copper Coil / Helical Antenna | | **Superheterodyne Receiver** | High-sensitivity circuit used to filter noise and stabilize frequency. | SYN480R / LR480 | | **Crystal Oscillator** | Provides a stable clock frequency for the RF decoding process. | 6.7458MHz or 13.56MHz | | **Relay / Switching** | The output stage that physically turns a device ON or OFF. | 10A 250VAC Electromagnetic Relay | --- ### 2. Technical Specifications Most JR-00-R modules follow these standard electrical parameters: * **Operating Voltage:** DC 3V - 12V (Low voltage versions) or AC 85V - 250V (Mains versions). * **Frequency:** Usually **433.92 MHz** (standard) or 315 MHz. * **Modulation Type:** **ASK / OOK** (Amplitude Shift Keying). * **Sensitivity:** Often ranges between **-105dBm to -110dBm**. * **Standby Current:** Extremely low, typically **< 5mA**. --- ### 3. Pinout and Connection Logic While specific board layouts vary, the JR-00-R series generally follows this logic: 1. **VCC / L:** Positive Power Input (DC) or Live Line (AC). 2. **GND / N:** Negative Ground (DC) or Neutral Line (AC). 3. **OUT / DATA:** The pin that sends the high/low signal to the controller. 4. **Learning Button:** A tactile switch used to pair the receiver with a specific remote control. 5. **LED Indicator:** A small SMD LED that flashes to confirm signal reception or pairing mode. --- ### 4. Circuit Behavior (Programming) The JR-00-R modules often support three electronic modes via the **Learning Button**: * **Momentary:** The output stays active only as long as the remote button is held. * **Toggle:** Press once for ON, press again for OFF. * **Latched:** One button turns it ON, a different button turns it OFF. ---
