KDraz on DEV-08937 - LilyPad XBee
Thanks for your response. I programmed the lilypad using the FTDI but then removed it to test the Xbee functionality. I know it's not a problem with my sketch because it works using the Uno and it's...

Hi!Two questions -If there is no system/load connected to the power cell, will the battery still drain or must I install a SPDT switch? I'm thinking of using it as a solar charger/batterypack.. Can I...

I'm using one of Sparkfuns batteries and maybe the under voltage protection is enough to leave it connected to the Powercell (such a pain to remove the JST connector).

Would SFE ever consider making a breakout like this that had DTR and RTS (instead of CTS)? That would allow for 2 digital outputs from the PC, which is great for bootloaders that need test and reset...

Sorry about the problems. Are you getting any lights on the XBee module?

Also, can you verify that the LilyPad Arduino is working properly, for example by blinking the LED on D13?

It would be awesome if Sparkfun made a step-down circuit akin to this step-up and in the same form factor. I know that Sparkfun carries a step down chip, but it's not the same:...

Thanks for the reply, I'll try that idea.

Also (sorry) from something you wrote above, you should have four wires going to the XBee: 5V to the "+" pin, ground to the "-" pin, and TX and RX.

We already do! BOB-00718 breaks out all of the FTDI chip's pins; I use this one a lot for programming ARM processors with Flash Magic.

If I was to make an IR illuminator for night-vision viewing through a phone camera with all of these, would it be bright enough? Also, would 850nm be better despite the visible red glow?

Yes I am getting the blinking red LED on the Xbee (and I went ahead and connected + to 5V even though it still lit up without it). I am also getting the green LED on the Lilypad. Is it possible that...

It's possible that the AAA can't supply enough power to both, especially if it's a weak battery, etc., but it should work. The XBee is the thing here that needs the most power. Be sure you're using a...
