The LED blinks at about 1Hz while it's searching for satellites and blinks once every 15 seconds when a fix is found to conserve power. If you want to have an LED on all the time, we also provide the FIX signal out on a pin so you can put an external LED on.\u003cbr\u003e\u003cbr\u003eTwo features that really stand out about version 3 MTK3339-based module is the external antenna functionality and the the built in data-logging capability.

The ouput from the amp is about 2Vpp max on a 1.25V DC bias, so it can be easily used with any Analog\/Digital converter that is up to 3.3V input.
