Today I finally sent a PCB I have been working on for a couple of weeks to manufacturing. It is a wireless sensor node based on a Cortex M0+ processor and an XBee ZigBee radio module. In addition to the main board with the processor and the radio, there are a couple of break-off sensor boards for measuring temperature, humidity, soil moisture, AC current etc. Here is a screenshot of the board:

More information will follow when I have assembled and programmed the board.
