➔ Audio Amplifier Ic : 2 Pis
➔ Audio Amplifier Ic No: CS5230EA - CA45
➔ LED: Charging Led (Red) / Audio Running And On LED (Blue, Red, Green)
➔ Charging IC: 5v Convert 4.5 Volt
➔ Resistor: As Needed
➔ Capacitor: As Needed (Non Polarized)
★ Crystal IC:
➔ Frequency: 24.000 MHz
➔ Crystal IC Type: SMD
➔ Crystal IC Total Pin: 4 Pin
Crystals provide a precise clock frequency to control timing in circuits. The 24.000 MHz crystal oscillator is surface-mounted (SMD) and has 4 pins, likely including connections for power (Vcc), ground (GND), and output.
★ Audio Connector:
➔ Type: Auxiliary (AUX)
➔ Total Pin: 4 Pin (Connection Pin: 3 Pin)
The auxiliary (AUX) connector is typically used to connect external audio sources, such as phones or media players, to the amplifier. Even though the connector has 4 pins, only 3 of them are used for connections:
Left Audio Channel (L)
Right Audio Channel (R)
Ground (GND)
The fourth pin might be unused or reserved for grounding or shielding purposes.
★ Memory Card Slot:
➔ Memory Card Slot Install Quantity: 1
➔ Type: Mini Slot
This memory card slot is designed to hold a memory card. Given that it's described as a "Mini Slot," it's likely compatible with a miniSD or microSD card, which can be used to store audio files, configuration data, or firmware.
➔ USB Connector: Only Audio Support
➔ Swith : 4 Pis (On/Off _ Volume +/Mp3 Next _ Volume -/Mp3 Reverse _ LED Function
➔ Capacitor: 3 Pis (Polarized) 10V, 470uf (Microfarad)
➔ Audio Output Slot: 2 Pis (5 Watt-10 Watt Output One Slot, Total 2 Slot Upto 20 Watt Total )
➔ Battery Slot: 1 Pis (4.2, 5Ah Supply)
★ Buttons:
➔ Total Install Button Quantity: 4 Buttons
➔ Power Button (P/P): On/Off switch with 4 pins: 2 connected to ground (GND), 1 not connected (NC), and 1 providing a signal to the control IC.
➔ Previous Button (PREV): This button is used to navigate to the previous track or function. It also has four pins: 2 connected to GND, 1 NC, and 1 providing a signal.
➔ Next Button (NEXT): This button functions similarly to the previous button but allows you to move to the next track or function.
➔ Mode Select Button (MODE): Used to switch between different modes (e.g., AUX, Bluetooth, Radio), following the same 4-pin configuration.
▶ Extra Information:
★ Audio Signal Processing:
The Audio Generator IC (AB20BP06664 - 69D4) generates or processes audio signals. These signals are then passed to the CS5230EA—CA45 Audio Amplifier IC, which boosts them to a level sufficient to drive the speakers.
★ Control and User Interaction:
The board includes four buttons for user interaction, allowing power control, track navigation, and mode selection. Each button connects to the control IC, providing signals that trigger specific functions.
★ Connectivity and Inputs:
The AUX connector allows external audio input, while the memory card slot supports stored audio playback. The microphone enables voice input for additional functionality.
★ Output and Indicators:
The dual speakers output the amplified audio signals, while the LEDs provide a visual status of power, audio activity, and charging.
