Greetings!
I've been using the LiPower Shield to power an Arduino Pro Mini. I connect a 3.7 volt 850 mAh LiPo battery, move the switch to ON, and the power light glows red. The Arduino program starts and everything is as expected.
In between the LiPower Shield and the Arduino Pro Mini (which is mounted on a ProtoShield Kit board), is the Ardumoto shield. I wanted to extend the built-in indicator (I/O pin 13) so I connected 13 from Arduino Pro Mini to 13 of the ProtoShield Kit. In the stack, 13 connects to DIRB on the Ardumoto shield. I placed a 1k resistor and LED on 13 of the Lipower Shield and connected the other end of the LED to ground. When I moved the power switch to ON, the power light did not illuminate immediately. It slowly brightened and then dimmed. I thought I smelled a burning capacitor (possibly the 22uF after the boost circuit).
Might you have some ideas why the Lipower Shield has changed behavior? From the present behavior, might I consider the Lipower Shield inoperable?
Thanks!
Joe
