Feature:



This product uses 5.0 Bluetooth DC3.7V-5V power supply, through the secondary development of peripheral hardware, the maximum power can be configured to reach 10W (5W*2), and it can also be modified for external power amplifier (outside audio output from 3P socket); PCBA size 40MM *34MM*9MM (including seat); Micro-wave power switch control; hands-free call and external buttons (reserved, customized production when needed; button value-temporarily playing 0 ohms, the first song 12K, the next song 47K), Bluetooth Equipment product ID: YMX-868BT
Power supply: DC voltage (3.7-5V), the current must be above 1.5A-2A; 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 on when it is fully charged)
Please choose the original manufacturer for the charger. Not only the current cannot keep up, but also the constant current is unstable. It is easy to damage the battery and the board. Pay attention!

Selection criteria requirements:
Power requirements: DC voltage 3.7V-5V, voltage cannot be higher than 5V; current 1.5A-2A; (Special reminder if you use 3.7V lithium battery, please ensure that the lithium battery and discharge can reach 1.5A, some lithium batteries have voltage but not current Please use it with caution if it is stable or does not meet the requirements; otherwise, it will keep restarting or the sound quality is not good, such as broken sound/distortion)

Speaker requirements:
1. (Satellite) left and right channel sub-box speakers: use 4 ohms (Ω)/5W*2 full-range speakers (special reminder if you use 3.7V lithium batteries, please ensure that the lithium battery and discharge can reach 1.5 A, some lithium batteries have voltage but current Please use it with caution if it is unstable or cannot meet the requirements; please choose 4 ohm (Ω)/3W*2 for the speaker
2. 3P socket OUT audio output: if you need to connect other power amplifiers, you can connect from here (the middle audio ground, left and right are L and R respectively

Bluetooth connection: Turn on the phone's Bluetooth detection from the settings menu, so that the phone can be detected by the device, and then enter the Bluetooth menu-search for devices or paired devices, after searching (YMX-868BT), "touch pairing "will also be heard "Connect successfully or beep" sound completes the pairing;
Note: It is not a smart phone (Android system) to enter the password -0000; the product Bluetooth device name is YMX-868BT
pay attention:
1) The red 2P seat BAT is connected to the positive pole of the power supply from DC3.7V to 5V+, and the GND is connected to the negative pole; the white 2P seat is connected to the speaker from bottom to top LO-/ L-O+, and the white 2P seat RO-/R-O+ is connected to the speaker
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 when connected to two speakers. Lithium-powered speaker with 4 ohms 3W+3W, regulated The power supply 5V speaker is equipped with 4 ohm 5W+5W. If the current is not enough, there will be skipping or Bluetooth instability, the motherboard will keep restarting or the sound quality/broken/distortion and other bad phenomena (If this problem occurs, please check your power supply); The voltage cannot be higher than 5V, otherwise it will damage the main chip, power amplifier IC and related components, please pay attention
3) Audio output: 3P OUT audio output can be modified for external power amplifier, the middle is the audio ground, the left and right are L and R respectively
