Based on JQ8900 module, it can be used for voice broadcast, etc.

Overview

Developed and optimized based on the JQ8900 module, it can be used for voice broadcasting, etc.

At present, the board still has an unknown bug , and the flash chip cannot be read normally after plugging it into the computer. Therefore, I open sourced it to seek help and suggestions from the big guys . The main control chip is JQ8900, which is not available in Lichuang Mall. The power amplifier chip is 8002A. This chip is cheap, but the sound quality is not good. We will consider a version to replace other power amplifier chips in the future, but at this stage, we mainly consider solving the problem of not being able to flash the chip. The flash chip is w25q128 chip, other similar types are also available. The difference lies in the chip storage size.
