The **00-R** (often associated with specialized sensor modules, resistor series, or specific radio-controlled hobby parts depending on the manufacturer) most commonly refers to the **00-R series of high-precision sensors** or generic surface-mount components (SMD) with a "00" ohm (zero-ohm) jumper designation. Below is an overview of electronic parts associated with this designation, focusing on the most common industrial applications. --- ## 1. Zero-Ohm Resistors (00-R / 000) In PCB design, a component labeled "00-R" or marked with "0" or "000" is a **Zero-Ohm Resistor**. It acts as a bridge or a jumper. ### Key Characteristics | Feature | Description | | :--- | :--- | | **Resistance** | Theoretically 0Ω (Actual: <50mΩ) | | **Function** | Connects two traces on a PCB, allowing automated pick-and-place machines to install jumpers. | | **Use Case** | Configuring different circuit options on a single PCB design without changing the board layout. | --- ## 2. Remote Control (R/C) Receiver Parts In the context of hobbyist electronics (like the **Double Eagle** or **WLToys** series), parts labeled **00-R** often refer to the Receiver/Mainboard unit. * **RF Module:** Operates usually at 2.4GHz to receive signals from the transmitter. * **ESC Integration:** Often includes the Electronic Speed Controller (ESC) to drive the motors directly. * **Power Input:** Typically rated for 3.7V (1S) or 7.4V (2S) Li-ion batteries. --- ## 3. High-Precision Sensor Modules (00-R Series) Some manufacturers use "00-R" as a suffix for industrial sensors, particularly those measuring pressure or rotation. ### Common Specifications | Component Type | Common Specs | Application | | :--- | :--- | :--- | | **Potentiometers** | Linear/Logarithmic taper | Volume control, position sensing. | | **Rotary Encoders** | Incremental pulses | Digital menu navigation. | | **Pressure Transducers** | 0-10V or 4-20mA output | Industrial automation. | --- ### Comparison of 00-R Component Types 1. **Passive Components:** Fixed jumpers used to bypass sections of a circuit. 2. **Control Boards:** The "brain" of small electronic vehicles, managing power distribution. 3. **Interface Parts:** Connectors or sockets (specifically in legacy military-spec parts). ---
