Bluetooth 5.0 Amplifier Board Mini 5W*2 Stereo Power Amp Decoder Audio M.PI
DESCRIPTION:
Product description:
The product adopts 5.0 Bluetooth DC3.7V-5V power supply, the maximum power can be configured to reach 10W (5W*2), and the external power amplifier can be modified, please connect it from the 3P socket OUT audio output;
PCB size 40MM*34MM*9MM (including nest);
Micro wave power switch control;
Bluetooth 5.0 device product ID: YMX-868BT
Power supply: DC voltage (3.7-5V), current should be 1.5A-2A or above; USB is the charging input (when the lithium battery is plugged into the red power socket, it can be charged from here; the red light is on when charging, the red light is not lit )
Please choose the original authentic charger, the poor quality of the power supply can not keep up with the constant current instability, easy to damage the battery and board.
Power requirements:
Voltage DC voltage 3.7V-5V, voltage can not be higher than 5V; current 1.5A-2A; (note: 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 or bad.
Speaker requirements:
(Satellite) left and right channel sub-box speaker: select 4 ohm (Ω) / 5W * 2 full-range speaker   (note: if using 3.7V lithium battery, please ensure that lithium battery discharge can reach 1.5A, some lithium battery has voltage but current is unstable Please do not use if you can't meet the requirements; please choose 4 ohms (Ω) / 3W * 2 for the speakers.
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: not a smartphone (Android) to enter the password -0000; product Bluetooth device name YMX-868BT
Note:
1) Red 2P seat BAT is connected to the power supply positive DC3.7V to 5V+, GND is connected to the negative pole; white 2P seat from bottom to top L-O-/L-O+ is connected to the speaker 1, white 2P seat R-O-/R-O+ is connected to the speaker 2
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 cannot be higher than 5V, otherwise the main chip and the power amplifier IC and related components will be damaged.
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
4) If you will connect or use lithium battery (3.7-4V power supply), do not add this component (IN4007), so the voltage will be reduced by about 0.7V, read U disk and SD card will not read, you can Directly cut off the IN4007
Package included:
1Pcs+ 4*Cables
