I bought an Electric Imp 003 from DigiKey and two new AA batteries. When I put in the batteries, there are no LED lights. Is the 003 supposed to work on just batteries?
Yes, it will. You need to move the jumper to select the boost supply vs the buck supply.
See https://electricimp.com/docs/hardware/imp003evb/ and the jumper highlighted by the brown box.
Thanks! That worked. Maybe the Getting Started Guide should actually say what the jumper does? I had no idea what boost/buck means.
Good point, we’ll make that clearer
