Notes:
{1} Where the onboard regulator option is mounted this pin is connected to the output voltage of the
{2} VCONT is the internal amplifier gain control voltage, resistive external loading to ground can reduce
{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
onboard regulator option and NOT to the output voltage VREG_OUT of the EM250
the amplifier gain and therefore lower the maximum available module Tx output power. For most of
the applications this pin is NOT connected and the amplifier is working at maximum gain.
Controlling the maximum output Power can also be achieved in software.
