Bartendro does not boot
A couple of days ago boot up started failing, first we thought we had too many pumps(13-15) plugged or that the ethernet wires were too long, because when we unplugged them all we were able to boot raspberry pi and bartendro.
Today raspberry pi has the power light on, but no signs of trying to boot. Nothing happening on bartendro board either. We have checked switch, power supply, raspberry pi (we replaced it), SD card image, no success, any ideas? also, what is the coin battery for?
Is this a good question?
