TinyDuino Processors & TinyShields / Not powering on

« on: January 16, 2016, 10:47:48 PM »

With a coin battery installed the card power-on LED will blink maybe 1 out of 10 times when powered on. The board  with the attached USB shield does not provide a connection to the host system. The host system does work with other Arduino boards along with the USB cable. Any help would be appreciated. Also this is the board with the coin battery. Does anyone know the part I need for the external battery connector?
