{1} Where the onboard regulator option is mounted this pin is connected to the output voltage
{2} TXD is the UART output, RXD is the input
{3} RTS/CTS handshaking is selectable in firmware. See the AT Command Manual.
{4} Pad 38 is connected to GPIO7 but is not used by the Telegesis firmware
of the onboard regulator option and NOT to the output voltage VREG_OUT of the EM250
