Core Ink
-
Hi,
Appreciate any help on this... I'm trying to switch a relay on/off on my Core Ink, and it's working fine while the Core Ink is connected on USB, but as soon as I unplug, it stops. Presumably this is because I only get 5V supply when on USB? How can I drive a relay from the battery on board the Core Ink? is there any 3V or 5V output from any port that should work when on battery?Thanks,
Anthony. -
Hello @amxd55
if you have a look at the sticker on the back of M5 CoreInk you'll see that
3.3 Vand5 V OUTare powered by USB or battery. I'd use a multimeter to measure between5V OUTandGND. It should read 5 V in both cases - USB or battery. If on battery the 5 V are not there then maybe the battery is flat?Thanks

thanks Felix for your help I now have it working... something was going wrong between moving from USB to battery.
