Feature

●This product is a 5.2 BT pair box function (modules); the voltage is 5 V / the current is 2 A, the power supply is processed by secondary development of peripheral hardware, the maximum power can be configured to 5 W, and the BT device name is ymx-868bt
●USB is the charging input; 5V in can be charged from here; the red light will light up during charging, but the red light does not light up when fully charged). Please choose the lithium battery with protective board; please choose the original manufacturer for the charger, Shanzhai can not only not keep up with the current, but also cannot maintain a constant current, which can easily damage the and the board. Watch out!

Description

BLASHRD Special Attention: 1. Bat + is connected to the positive pole DC 3.7 V to 5 V +, GNT - is connected to the negative pole; 2. The operating voltage of the lithium battery is 3.7V, or the DC of the regulated power supply is 4.5-5V, and the current is 600-700mA when a horn is connected. About 1.5-2a when horns are connected. The lithium-powered horn is equipped with 4 Ω 3 W + 3 W, the regulated power 5 V horn is equipped with 4 Ω 5 W + 5 W. If the current is not enough, some bad phenomena occur, such as the voltage should not be as 5 V, otherwise the main chip, the power amplifier IC and associated components will be damaged. Please note 3. Wiring horn: white 2p seat SP - / SP + from bottom to top, l-o - / l-o + connected to horn 1; white 2 seat SP - / SP + from bottom to top, R-O - / R-O + connected with horn 2 colour: as shown material: PC + metal Package contents: 1 x audio amplifier board. Only the above package content, other products are not included. Note: Due to the light reflection and monitor settings, the colour of the item in the photos may be slightly different. The allowed measurement error is +/- 1-3 cm.
