Add a switch to your micro:bit or lipo battery projects! This switch connects between a power supply that uses a JST plug, like a 3.3V micro:bit battery pack or a lipo 3.7V battery used for boards like the WEMOS D32. Adding a switch to your micro:bit prevents breakage from plugging in and unplugging the battery pack in your classroom or code club. Note: be sure to use the correct voltages with your devices e.g. a lipo 3.7V battery is too high a voltage for the micro:bit. Read more..
