Click on the upper right corner to open it in the editor and you will see the schematic diagram and pcb board.
The bill of materials is in the attachment
. If there is a Supplier Part in the bill of materials, you can just buy components with the same package. If there is no Supplier Part, it is a copper plate that I drew myself. It is recommended that you buy M2 pad screws for welding
screws. It is recommended that you buy the size in the picture for nuts. Since the thickness of a single plate is 1.6, the pin length can be slightly longer for easier welding. A pin length of 1.5 means it is a bit difficult to weld. .
Regarding the battery, it uses a rechargeable polymer lithium battery, as shown below. It is recommended that you buy a smaller one so that it can fit. The following is the size of my battery. Please ensure that the thickness of the battery does not exceed the height of the nut in the picture above. It is best to leave a certain margin
for the connection between the battery and the board. The following is the slot for connecting the battery on the board. The model is XH2.54 horizontal sticker, so the connecting terminals for connecting the battery must also match the
following. Please ensure that there are bulges. On this side, the red wire is on the left, as shown in the picture, and then welded to the battery wire, that is, the red wire is soldered to the red wire, and the black wire is soldered to the black wire, so that it can be directly plugged into the board.
