The **TG-B6-R** typically refers to a high-performance **Wireless Gamepad/Controller** (often associated with brands like Terios or generic Bluetooth controller manufacturers). Its internal electronic architecture is designed to bridge the gap between human input and digital signals for PC, Android, and console platforms. --- ### 1. Core Electronic Components The internal PCB (Printed Circuit Board) consists of several critical subsystems: | Component Category | Part/Function | Description | |:---|:---|:---| | **Main MCU** | 32-bit ARM Cortex-M Series | The "brain" that processes button inputs and manages the Bluetooth stack. | | **Connectivity** | Bluetooth 4.0/5.0 Module | Handles wireless pairing and low-latency data transmission. | | **Power Management** | Li-Po Charge IC | Regulates voltage from the USB port to charge the internal 3.7V battery. | | **Motion Sensing** | 6-Axis Gyroscope/Accel | Detects tilt and rotation for motion-controlled gaming. | | **Haptics** | Dual Asymmetric Motors | DC vibration motors with offset weights for tactile feedback. | --- ### 2. Input Subsystems The TG-B6-R translates mechanical movement into electrical data via two primary methods: #### A. Analog Inputs (Joysticks & Triggers) The thumbsticks and "R2/L2" triggers use **Potentiometers**. * **Mechanism:** As you move the stick, a wiper slides across a resistive track, changing the voltage output. * **ADC:** The Main MCU uses an Analog-to-Digital Converter to turn this voltage into a coordinate (X, Y). #### B. Digital Inputs (Buttons & D-Pad) Standard buttons (A, B, X, Y) utilize **Conductive Rubber Membranes**. * **Mechanism:** Pressing the button pushes a carbon-coated rubber pad onto two exposed copper traces on the PCB, completing the circuit. --- ### 3. Power Specifications The device is engineered for low power consumption to maximize battery life during gameplay. * **Battery:** Usually a 400mAh - 600mAh Lithium-Polymer cell. * **Operating Voltage:** 3.3V - 4.2V. * **Sleep Mode:** The electronic firmware includes an auto-off timer (usually 5-10 minutes of inactivity) to cut power to the Bluetooth radio and LEDs. --- ### 4. Connectivity Modes (Firmware Logic) The electronics support multiple "Handshake" protocols depending on the button combination pressed during startup: ```json { "Android_Mode": "HID Protocol (Standard Gamepad)", "iOS_Mode": "MFi / DualShock 4 Emulation", "PC_Mode": "X-Input (Xbox Controller Emulation)", "Switch_Mode": "Pro Controller Protocol" } ``` ---
