Out of box

Moteinos come without any soldered headers or antennas. Without the wire antenna the range will be only a few feet, and while this is OK for testing purposes it’s recommended that an antenna be soldered before real application use of the transmitter. The provided wire monopole antenna has to be soldered to the “ANT” pin hole (just above the FLASH chip) to achieve any usable┬árange. Regular Moteinos will come with a 1×6 male header that you have to solder before you can power it and upload sketches through an FTDI Adapter. Moteino-USB has built in USB so you only need a mini-USB cable for programming.
