• Leave 1mm all round module (i.e. PCB footprint area of 25x35mm)
• PCB holes - 1.2mm or socket strips
• Keep AF track away from RXD & TXD - to avoid cross talk.
• Put a test point on the AF pin for simple radio checking with a scope.
• Ground plane all unused PCB area around and under module.
• Position module and antenna as far from high speed logic and SMPS as possible
• Microprocessors with external data/address busses ALWAYS cause interference.
• Provide LED status lights on TX, RX & CD (direct or by plug on test PCB)
• For complex networks - provide software test routines for :-continuous RX, continuous TX, loop test,
• The BiM-can (fig. 11) is available and may be used for shielding to achieve an optimal radio
