Power supply voltage: 5V
1. Imported chips are used for more stable frequency and pulse width
2. Double layer FR-4 1.2T-PCB board, with stable and more reliable PCB quality
3. Increase the emission coil, enhanced 28 coil emission coil, and increase the emission range
4. The board supports two power interfaces: TYPE C (supports forward and reverse insertion) and USB Micro, so you no longer need to worry about finding different charging cables
5. Original protection circuit, adding high-power TVS electrostatic protection tube to prevent hand and air static electricity from damaging the chip.
6. Add a PPTC self recovery fuse to prevent the power supply of the board from being completely cut off after a short circuit occurs. When the short circuit is resolved, the fuse automatically
