How to assemble

To minimize risk of damaging the board with static electricity, only hold it by edges and do not touch components. Click on the banner above to learn more about risks of ESD.

Start with the front panel. Peel off the protective foil (ideally only from the inner side, so the front side stays protected against scratching during assembly). Watch for correct orientation, then put two steel screws into the holes, and from the other side, install two brass washers on the screws.

Then put one black Teflon washer on each screw, over the brass washer. Set the buttons in place.

Now set the board on top, and add two more black Teflon washers on each screw.

Install second acrylic plate, don't forget to peel off the protective foil and watch for correct orientation.

Finally, add two steel bolts and tighten everything together. Be careful to not overdo it, so the plates do not crack. Make sure the plates and board are aligned well. Add four silicone bumper pads too.

Congrats, all done!

Alternative for Li-Po

If you are adding a Li-Po cell, instead of two bolts, add brass spacers. There should be pair of 5mm and 6mm spacers in your kit. There are also extra two black Teflon washers, if you need to add another 1mm somewhere.

To enable built-in charging circuit, you need to close two solder jumpers. Also, be careful to connect the battery wires correctly. Larger pads are there to support a JST connector like this one, but they have no electrical connection.

There are two pads for each battery pole (one is for wire terminal, the other one for JST connector), they are internally connected so if you solder wires directly, it does not matter which one you use - or you can solder on both to get a more reliable joint.

When installing Li-Po cell, check that the wires are soldered well, and there is no risk of short circuit. It might lead to violent discharge, heat up, melt, set something on fire - if the cell does not have a protective circuit. Make sure the cell does have the protection - you can find more info at the end of this article.

Micro-SD Card

The card is inserted this way.

The slot is under the SET button.

The card holder is a push-push type, meaning it gets locked when you you push it in.

To release it, push again, and it will get released and ejected.
