Instructions for use: 1. Connect the speakers The speakers at both ends of the wire at the end of the line are connected to the audio amplifier board port output, the left channel sound is connected to the LOUT port of the power amplifier board, and the cathode is connected to GND. The positive line power amplifier is correctly wired on the ROUTE port, and the cathode is connected to GND. 2. Connect audio source Use a 2-core audio cable, connect to the input of the 3p audio amplifier board, and connect the other end of the audio cable plug to the sound source for example, computer, mobile phone, MP3, DVD, etc. 3. Connect the power cord Everyone can cherish the 1.8-12v DC output using power supply/battery/charging adapter, etc. Connect the two DC power cables to the 2p power port on the edge of the amplifier, with the positive pole to VCC and the negative pole to GND, It is important to figure out that the connection is negative, not blindly wiring. If they meet, they may hold the power amplifier board. 4. Play music Turn on the power, the amplifier board is in working condition; you can adjust the volume knob according to your preferences.
Note: There may be slight size deviations due to manual measurement, different measuring methods and tools. The picture may not reflect the actual color of the item because of different photographing light, angle and display monitor.

LILYGO® TTGO T-U2T USB To TTL Automatic Downloader CH340K
LILYGO® T-U2T USB To TTL automatic downloader CH9102Currently only
compatible with Windows , Mac systems of 10.15 and below
LILYGO T-U2T is the abbreviation of USB To TTL,
The original intention of this product design is that every time you design an ESP32 circuit board, you will find that the same circuit of usb To TTL appears on the schematic, especially when designing a small-sized circuit.
This circuit occupies a lot of space, and it also increases the cost, so we want to change it,
Finally we discovered that each product also [...]
