Still works great.\r\nThen I removed the battery, installed the board into a box, then plugged the battery back in.\r\nNo go.\r\nI expected it would boot and run just as it does using the Expansion Board 2.0\r\n\r\nPut 5V USB power in, boots again.\r\n\r\nThen I tried the RGB test LED sketch.\r\nWorks great with 5V supply.\r\nRemove the 5V supply and run from battery - still works great. \r\nHit the reboot button, it won't boot.\r\n\r\nWhat I also found was when plugging the battery in the USB LED glows (half brightness), which defeats being able to run the Expansion Board from battery in deep sleep for long periods (LED will drain the battery quite quickly).\r\n\r\nI've not tripped upon any differences in the 2.0 to 3.0 that suggest the USB LED can be disabled or should be on when the battery is connected. Also, how can I boot the board with the battery as the primary power source?\r\n\r\nAny ideas?\r\n\r\nThank you!"}}
