JBL Charge 6 Internal Components and Bluetooth Antenna Identification
Overview
This document details the identification of internal electronic components and the Bluetooth antenna assembly for the JBL Charge 6 portable speaker. The information is derived from visual inspection of the device's internal structure, including printed circuit boards (PCBs) and associated parts.
Bluetooth Antenna Assembly
A dedicated Bluetooth antenna assembly was identified. It is labeled as:
- Part Identifier: DX-Charge6-BT-V02T
- Label: BT Antenna
The assembly consists of a flexible cable connecting to a small antenna element, often secured with adhesive backing.
Main Printed Circuit Boards (PCBs) and Components
Multiple printed circuit boards house various electronic components. Key components and board identifiers observed include:
