Product Features
1. Default shipping mode (two-wire serial port control mode)
Supports MP3/AV/WMA format audio, this upgrade no longer supports the old AD4 format
Module power supply 3.3V-5V
Supports TF card, USB flash drive, SPI-Flash
2. Module follow-up flashing mode (MP3 control mode)
Procedure upgrade steps:
1. Prepare a USB flash drive or T-card
2. Format
3. Copy the upgrade document to the prepared ∪ disk or T card
4. Power on the circuit board|
5. Insert USB flash drive or TF card
6. Wait for 10-20 seconds, when the speaker emits a "wuwuwu" sound similar to vibration (which may not be audible, but can be felt by touching the speaker diaphragm with your fingers), indicating that the upgrade is complete
7. Unplug the USB flash drive or TF card and use it normally
Attention: If you do not hear the "wuwuwu" sound for more than 30 seconds, please repeat steps 4, 5, 6, and 7
