• We are a professional design, development, production and gross sales manufacturing unit We can design, grow and convey consistent with your requirements; Welcome OEM Note: The module chip mannequin quantity is random; Different batches have different numbers Special note: the module ought to be powered from the pink 2P energy supply seat, and can't be powered immediately from the USB energy delivery (here, it supports detection, and can't pressure the loaded high-power) This product is a five BT TWS case matching function (optional); Support 4 euro 3w*2 or 5w*2 speakers; Support 3; Hands free call; 3pout output The voltage is 5v/ the present is 2A After secondary advancement of peripheral hardware, the utmost strength can be configured to arrive 5W The Bluetooth gadget call is ymx-878bt Power supply: DC DC voltage (3) and current above 2a-3a; USB socket is a charging input socket; When charging, the purple mild is on, and when fully charged, the purple gentle isn't on), please select lithium battery with defense board Statement: The payment is 1 pcs If TWS operate is used, you need to buy 2PCS, and two BT modules must be used (touch the foremost signal pin with the light change or twine to contact GND grounding, that is, TWS is attached through mutual scanning; word that this is a touch, not a long press brief circuit); The module can only have typical BT purposes When the board linked to TWS is mono; When TWS is disconnected, the board is stereo Operation method: 3P seat out output: exterior power amplifier board can be related The middle of 3p is audio ground, and the 2 sides are r/l respectively three input: when the 3 audio cable is plugged in, it is the aux enter mode (BT is disconnected); 3 the headphone stand can't change the line randomly since it has the operate of detection Toll unfastened call: routinely answer the decision after the incoming call rings The TWS operate can solely be used for calling on the motherboard TWS pairing box: (touch the main sign pin with a light change or twine to GND, that is, TWS is hooked up via mutual scanning; notice that the touch is not a long-term short circuit) At this time, automated pairing connection (after profitable connection, there will be a "beep" sound, and at the same time, one board will flicker frequently / the opposite board can be on for many years Two PCBA BT modules should be turned directly to operate this function After scanning pairing, it will likely be linked mechanically About the key frame: two PCBA BT modules are used on the identical time If the host is disconnected (the blue light flashes frequently after pairing connection is the host, and the blue gentle stays on for many years is the frame), the two modules are disconnected on the same time After connecting to the cellular telephone once, it defaults to the current host BT connection: turn on the BT detectability of the mobile phone from the atmosphere menu in order that the cellular telephone would be detected through the device, after which go to the BT menu - search for devices or paired devices After in search of the "touch pairing" of the ymx-878bt, you also can hear the "prompt tone" sound to complete the pairing; Requirements for choice conditions: Power requirements: Voltage DC DC voltage 3, and the voltage shall not be larger than 5V; Current 2a-3a; (special reminder: whenever you use a three lithium battery, please ensure that the lithium battery and discharge can reach 2A Some lithium batteries have voltage however the current is risky or can't meet the requirements, please use it with caution; otherwise, it will likely be restarted forever or the sound high quality can be poor, broken / distorted, etc) Horn requirements: When the power delivery is 5v/2v: (satellite) left and correct channel speakers: choose four Ω /5w full frequency speakers (special reminder: while you use a 3 lithium battery, please be sure that the lithium battery and discharge can attain 1 Some lithium batteries have voltage however the current is volatile or can not meet the requirements Please use it with caution; please choose to use 4 Ω /3w for the horn BT connection: switch on the BT detectability of the cellular telephone from the setting menu so that the cellphone would be detected through the machine Then go to the BT menu - search for instruments or paired devices, seek for "878bt" contact pairing "and hear the sound of" successful connection or prompt tone "to complete the pairing; Note: if it isn't a smart cellphone (Android system), input the password -0000; Product BT gadget call 878bt Special attention: 1) b+ is attached to the wonderful pole of power supply dc3 to 5v+, and gnd- is hooked up to the negative pole; 2) operating voltage: lithium battery 3, or regulated strength supply DC 4, recent (1a when one horn is connected; about 2a-3a when two horns are connected) Lithium powered horn is equipped with four euro 3w+3w, and regulated energy 5V horn is supplied with four euro 5w+5w If the current is insufficient, there'll be soar or volatile BT, the motherboard might be restarted all the time, or the sound quality is deficient / broken / distorted (please test your energy supply if there is this problem); The voltage should not be higher than 5V, otherwise the key chip, power amplifier IC and related components will be damaged, please notice 3) Sp-/sp+ from bottom to top l-o-/l-o+ connected to horn 4）Pay consideration to anti-static medication during DIY amendment The wire end must be in good contact, especially make sure you turn off the flexibility whenever you function The power supply can solely be grew to become on after the wiring is checked correctly Do no longer operate with energy on Don&;t touch those elements with digital wires be careful!
