This is the new autosampler node prototype. It uses the 12V autosampler battery to charge the lithium ion node battery instead of the solar panel, removing the need for the conduit and allows the node to sit inside the autosampler lid. Overall, this makes installation significantly easier and faster. Note: the battery currently only lasts about one week, so for hard to reach locations, this may not be the best solution. Future changes to the firmware should extend the battery life.
