### **Description**
Up for sale is a specialized electronic control board (PCB), identified as version **UNI_2_V0.1**, and its accompanying **heavy-duty knurled mounting thumbscrew**.
This board appears to be a crucial component from a high-quality piece of specialized equipment, likely in the audio, communication, or RF sector (given the U.FL antenna connector). The central brain is an **R52** microcontroller, and it features a very clean layout with multiple soldered wires, including a specific rainbow-colored input ribbon cable and several black output wires, along with a row of pin header connectors.
**Key Features & Component Callouts (See Photos):**
* **Processor:** R52 MCU (Marked clearly).
* **Version:** UNI_2_V0.1 (Silkscreen text).
* **Power Stage:** Features two large, robust white **35V 150µF electrolytic capacitors** for clean power delivery.
* **Wiring:**
* One side (Input): Pre-soldered multi-colored (rainbow) ribbon cable.
* Other side (Output): Multiple black wires and a distinct row of pin header sockets.
* **RF Port:** Features a miniature U.FL (also known as I-PEX) connector.
* **Mounting:** Includes the exact high-quality knurled metal thumbscrew shown, essential for mounting the board or the equipment it belongs to.
**Condition:**
This board is being listed as "New (Other)." It is clean, without signs of use or soldering, but it does not come in original retail packaging. It appears to be new-old stock or pulled from an unused, specialized unit. Please examine all high-resolution images carefully to confirm markings and condition against your required specifications. We cannot provide technical support for integration into your system. This listing is for the exact two items shown in the main image.
**Ideal for:** Specialized repair work, reverse engineering, or as a replacement part for water level controller or electronic projects
