#REDIRECT [[PineTime Devkit Wiring]]
 
The devkit comes with a set of wires you can use for connecting your programmer to the SWD pins. Most people use friction to make contact with the programming cable. Soldering the wires to the pinetime is not recommended, especially if you don't have a temperature-controlled iron and good confidence that you can do it - the thin PCB is fragile and easy to break. Current dead PineTime count due to such soldering gone wrong is '''3''' (update this number when suitable).
 
''' Read this about the battery: '''
 
You have two choices:
 
a) If you '''have''' a soldering iron and you're confident with using it, it is recommended that you remove the battery until you actually need it. Doing so avoids unnecessary charge cycles and strain on it. It can also potentially prevent issues with your watch not resetting properly. There's also the possibility that you could just connect a microswitch between the battery's positive side and the PineTime.
 
b) If you '''do not have''' a soldering iron or you're not confident with using it, don't disconnect the battery if you ever plan on using it. Don't bend the wires too much as they're thin, you won't be able to reconnect it. Keep in mind that keeping it connected during development will probably reduce the lifetime of the battery, it will also very likely backfeed power into your 3.3V pin - '''don't cause short circuits, don't leave the wire dangling!'''

The devkits have exposed SWD pins for flashing and debugging.
