Wiring instructions:
1. 12V connection: 2P socket(J6 position), Connect to 7V-12V DC, the red wire is connected to the positive pole of the power supply, and the black wire is connected to the negative pole of the power supply;(See the picture above for details)
2, 5P white seat(J5 position):5V connect to DC 5V positive pole(Current about 1A); GND, connected to the power ground; R-O, right audio output; GND, audio ground; L-O, left audio output.(Note: only audio output, not directly connected to speakers, need to connect to an amplifier)
Special note: The current is 600MA-1A, if the current is not enough, there will be phenomena such as skipping or remote control failure.(If you have this problem, please check your power supply); See the picture above. Pay special attention to the two sets of power supplies that cannot be connected to the product at the same time. The voltage cannot be higher than the highest voltage required by the product, otherwise the main chip and related components will be damaged!
hint:
(1), If it is modified to the car, only need to connect the 12V voltage to the 12V voltage input terminal of the decoder board at the position where the car is installed with the radio;
(2), If you directly connect the power supply on the battery, please use the 7812 or 7805 voltage regulator board to stabilize the power supply.
(3), If you directly connect the power supply on the battery, you can alsoA 4007 diode and a 2.2 ohm 2W resistor are connected to the anode for current limiting, see the picture below for details:
2. 3P seat: R-IN connects to the right sound channel of the external sound, GND connects to the external sound ground, and L-IN connects to the left sound channel of the external sound.
