YMX-868BT 10W Bluetooth Amp Board 40349 cm Black

YMX-868BT 10W Bluetooth Amp Board 40349 cm Black Description

Bluetooth 5.0 2*5W Amplifier Board AUX Audio Input Power Amplifier Board 3.7V 5V
Features:



It adopts 5.0 Bluetooth DC3.7V-5V power supply, and undergoes secondary development processing through peripheral hardware. The maximum power can be configured to reach 10W (5W*2).


Can be modified for external power amplifier (from the 3P block OUT audio output external).


Micro wave power switch control.


Hands-free calling and external buttons.


Power supply: DC voltage (3.7-5V). The current should be 1.5A-2A or higher.


USB is the charging input (the lithium battery can be charged from here when it is plugged into the red power socket; the red light is on when charging; the red light is not lit when the battery is fully charged).

Selection Criteria:

1. Power requirements: voltage DC DC voltage 3.7V-5V, voltage can not be higher than 5V; current 1.5A-2A; (specially reminded that if using 3.7V lithium battery, please ensure that lithium battery and discharge can reach 1.5A, some lithium battery has voltage but current is not Please use with caution if it is stable or does not meet the requirements; otherwise it will always restart or the sound quality is not good, such as broken sound/distortion.

Speaker requirements:

(Satellite) left and right channel sub-box speaker: select 4 ohm (Ω)/5W*2 full-range speaker (special reminder if you use 3.7V lithium battery, please ensure that lithium battery and discharge can reach 1.5A, some lithium battery has voltage but current is unstable Please use caution if you can't meet the requirements; please choose 4 ohms (Ω) / 3W * 2 for the speakers.

2. 3P socket OUT audio output: If you need to connect other power amplifiers can be connected from here (intermediate audio ground, left and right are L and R respectively.

Bluetooth connection: The mobile phone starts Bluetooth detection from the setup menu, so that the mobile phone is detected by the device, and then goes to the Bluetooth menu - search for the device or the paired device. After searching (YMX-868BT) "Touch Pairing", it also hears "Connected successfully or prompts" to complete the pairing;

Note: It is not the smartphone (Android system) to enter the password -0000; the product Bluetooth device name YMX-868BT.

Pay Attention:

 1) Red 2P seat BAT is connected to the power supply positive DC 3.7V to 5V+, GND is connected to the negative pole; white 2P seat is connected from the bottom to the upper L-O-/L-O+, and the white 2P is R-O-/R-O+.

 2) Working voltage lithium battery 3.7V, or regulated power supply DC DC 4.5-5V, current (600-700MA when connected to a speaker; 1.5-2A for two speakers). Lithium-powered speaker with 4 ohms 3W+3W, voltage regulator Power 5V speaker with 4 ohms 5W+5W. If the current is not enough, there will be a jump or Bluetooth instability, the motherboard will always restart or the sound quality is not good / broken / distortion and other bad phenomena (if you have this problem, please check your power); The voltage should not be higher than 5V, otherwise the main chip and the amplifier IC and related components will be damaged. Please pay attention.

3) Audio output: 3P block OUT audio output can be modified for external power amplifier, the middle is audio ground, left and right are L and R respectively.
