Xintang programmer, the pin header needs to be with pins, the package can be chosen randomly, just solder it according to the actual product
The pull-up resistor of R11 is not used and is not soldered.
It is recommended that the 5V output in the schematic diagram and the 500ma current of the fuse be added to the board when making the board later to prevent the back-end short circuit from causing damage to the board.
The C12 capacitor in the board version is placed upside down. As long as the soldering is normal, there will be no problem. The schematic and pcb have been corrected.
