    I could probably use a different pin also....
    Will try that!
    Thanks

    Oh sorry forgot to write that, this is a new button normally open.
    So it works as normal buttons work. Push and something happens.

    Any idea why this is happening?
    Push button is connected at pin B12 and 3.3 volt.
    Slide switch is connected to between battery plus and bat-pin. (powerswitch)

    Without the push button I don't need to keep the BTN1 pushed down to boot the Espruino.

    Charging CR batteries seems like a bad idea.
    I'm "new" to electronics, the reason for a schottky diode vs. a normal diode is that it's faster and has a lower voltage drop?
    A schottky diode is very cheap to buy, found one type that cost £0.07 but shipping it cost £3.

    So until the next time I place a order there, can a normal diode work?
    The obvious problem is that voltage will drop below 4.7v quicker with a normal diode than a schottky diode.

    So just to make sure I got it correct.
    Nothing 'bad' will happen with the Espruino, but in case you have something connected that does not like higher voltage that part will/might be affected.

    The reason I wonder is because I can't use the batteryconnector because it's blocked by the case.
    So either I use the pins or the backside of the batteryconnector. But that looks hard to solder on. Probably nothing I should even attempt :-)

    I tested using two CR 2025 (I think it was) to power the board on the pins and it worked fine.
    But as they run low the voltage will drop below 5 volts, and that was my concern, that it could dammage the board.

    Sorry to dig up an old thread.

    But what happens if you power the Espruino with, say 4 v and plug in the USB cable?
    Will it be a different outcome if you use the batteryconnector or pins on the board?

    Seems to work nice!
    I managed to get the wrong button when I was in the store.
    It's default on, and off when pushed. Doh'!
