Next it is necessary to walk through the steps required to assemble the hardware components of the kit. Begin by plugging the XBee into the XBee Grove Development Board. Make sure the board is not powered, either by the micro-USB or a battery, when plugging in the XBee module. Notice that the XBee has a flat edge and a more angular/diagonal edge. Match that footprint with the white lines on the board and carefully insert it, taking care not to bend any of the pins.
