Please note that this board layout may be used for both high- and low-power
applications, see also the bill of materials on the subsequent pages.
In case of ASK operation the solder bridge JP2 has to be shortened in the “ASK”-
position, in case of FSK modulation in the“FSK” position.
Solder bridge JP1between C1, C2 and C3) gives a choice of operating the board with
the on-board crystal as reference (“XTAL” shortened, i.e. close to C1 and C2) or with an
external clock generator (solder bridge shorts pads between C3 and C2).
