I try to power the espruino incl. a CC3000 WiFi module via a solar panel - the panel is charging a 12V battery and the 12V battery is connected to VBAT and GND of the espruino.
Now, the CC3000 was connected to VBAT, but I assume 12V would kill it. So I use the 3.3V pin on the espruino to connect the 3.3V pin on the adafruit CC3000 breakout.
It does not seem to work - maybe the CC3000 does not have enough power. But I think 5V is max for the CC3000. How would I connect the Espruino to 12V, but still supply enough power to the CC3000 - is VBAT with 12V an option?
