Depending on what you want to use for your power source there are a few

options here. You could use the on-board USB connector. Or you could

solder down a 2-pin JST connector, and plug battery (LiPo or AA) into the

board to make it mobile. If you go with either of those options on the imp

card Breakout, you’ll also need to set the jumper (the imp002 Breakout will

automatically select the higher voltage).

Note how the jumper is set. We’re using USB to power the imp in this

picture.

No need to set a jumper on the imp002 Breakout Board! We’re using USB

to power the imp002 here.

Alternatively, you can apply power straight to the headers labeled “VIN” and

“GND”. This pin bypasses the jumper and goes straight to the regulator.

Plug in the imp!

If you have the original imp card, plug the imp card in so the suspicious little

imp logo is facing up. If you’ve got power to the board, once plugged in, the

imp should start blinking orange. If there’s no blinking on the card, it’s

probably not getting any power. Double-check that the jumper is set

correctly.

If you have the imp002, the status LED should start blinking orange as soon

as you apply power.

What’s all that blinking signify? How do we get the imp connected to our

wireless network? Read on!

Blink Codes

The imp has an internal red/green LED, which is used to tell the world what

state it’s currently in. If you’ve just plugged the imp in, and haven’t told it

how to get on your WiFi network, it should be blinking orange (red/green

simultaneously). Here are the rest of the codes to look out for:
