The XBee Grove Development Board includes a microUSB connector and an FT232RL USB to
RS232 converter to communicate with the serial port of the XBee.
A green LED and a yellow LED show the status of the TX and RX lines.
The hardware flow control signals of the XBee (XBee_RTS and XBee_CTS) are connected to
the FT232RL device. Two serial 0R resistors disconnect the flow control of the chip if this
functionality is not needed.
The XBEE_DTR_N signal is also connected to the FT232 chip. XCTU uses this signal to enter
in the boot loader and will recover the module from incorrect firmware. A configurable 0R
resistor disconnects this signal if the functionality is not needed.
A three-pin jumper configures the serial port in a loop back mode, connecting the RX and TX
lines together. When positions 1-2 are closed, the serial port is configured in normal mode. In
this mode, the serial port of the XBee is connected to the microUSB connector. If positions 2-3
are closed, the serial port will work in loopback mode. In this mode, the data transmitted by the
XBee will be connected to the RX pin.
