Purchase Notes
1. This product features a split design with a decoder board mainboard and interface board. The mainboard integrates button controls and display functions but does not directly connect to peripherals. Instead, it uses a 2.0mm pitch ribbon cable to connect to the corresponding interface board. The interface board houses the appropriate sockets for connecting peripherals (e.g., LINE jack, USB port, TF card slot).
2. The decoder board operates at 4.5-5V. We recommend using a linear voltage regulator like the LM7805 to stabilize the power supply. Avoid using 3.7V lithium batteries, as their voltage is too low and unstable for this board.
3. Purchasing this decoder board does not include the main board schematic, PCB layout, source code, or other documentation. All available materials and instructions are provided on this page; no additional resources are offered.
4. Technical guidance for DIY modifications is not provided with this product. Buyers intending to modify speakers must assess their own modification capabilities before purchasing.
