AIR780E+STC15W4K56 network voice development board

Overview

Verify that the air780e4g module and stc15w4k56s4 have audio decoding and power amplifier sections, as well as lithium battery charging and discharging boost and buck circuits. The specific resistance value may not be the value in the schematic diagram. In the schematic diagram, resistors and capacitors mostly occupy positions. If you need specific values, you can leave a message and we will change them later (already changed, the specific values of resistors and capacitors in the power supply and audio parts, You can fine-tune it yourself during use)
